This commit provides a few fixes for quiz feature:

  * fix amount of karma won by the user in a quiz;
  * correctly display the fact that a subquiz was completed by the user instead
    of just looking like a non-completed quiz;
  * going on a previously completed quiz, good answers are hightlighted and
    inputs disabled;
  * effectively put the quiz in readonly mode if not a channel member.

Purpose of this commit is to perform a cleaning of

 * documentation course: add a new specific navigation for documentation
   course with a sort option and filters on slide types; clean overall layout
   of documentation course to have a better-looking result as this page was
   still not really updated;
 * lesson not fullscreen page: global layout and cleaning of not-fullscreen
   page to have a better-looking result. Notably related slides for

(notably banner, navigation, course / channel informations). Content list
layout displayed in training (orderable) is also tweaked and improved.

Commit 5798ca28 was assuming the vote and
comment access on slide was related to is_preview mode and was, consequently,
depending on each slide separately.

In fact, it's not because a slide is in preview mode that the user has the right
to vote for this slide. He must be course member to interact with this preview
slide, even if he has the right to read it.

So the vote and comment right are now computed at the level of the course,
and apply to all the slides of this course.

This commit also reviews and apply fixes on review - rating access.

Here are the applied rules regarding vote, comment and rating on course and slides:

A user can review a course:
- If allow_comment is activated on the course AND
- If the user is publisher OR
- If the user has enough karma AND is member of the course.

Note : if the rating is not allowed on the course, not only the button
to review must be hidden but also the entire rating composer.

A user can vote and comment a slide:
- If allow_comment is activated on the course AND
- If the user is publisher OR
- If the user has enough karma AND is member of the course.

Other fix applied is this commit :
- Avoid crash when no promoted slide : When going on course homepage
(documentation type), if no promoted slide, we got a internal server error.

Partial revert of commit 5798ca28
PR #31567

When a certification slide is display in no fullscreen
mode, the done button is clickable. Same applies to quiz
slide.
This commit prevents user to manually mark a slide as done
for slide type that requires an other action (submit answer,
pass survey, ...).

Task-1941250

As slides are returned in sudo to the template, the user rights were
checked via a can_access variable set in the template directly.
In order to disable the vote for user that cannot get access to the course
all the checks are now done in backend (also to avoid to get access to slides
in sudo mode with rpc calls). We add now, for each slide on the course view,
the access and vote rights to the template : can_access and can_vote.
Those two are computed in backend, using the user's access right instead of admin's.
But, as if the user is not member of the channel, he cannot get access to the
course slides (expect for Free Peview ones), so the check on can_vote
will crash. This is why we check the access rights before checking can_vote,
for each slides (as free preview slides are still accessible,
even if the user is not in channel members).

The vote widget is disabled if user's can_access or can_vote = False, enabled otherwise.
If user have access but have not enough karma, the controller will handle this
case and return an error to the user telling him he has not enough karma to vote.
If user can vote but cannot access, the controller will handle this
case and return an error to the user telling him he has no access to the lesson.

To avoid eLearning to be spammed, the comment, review and vote behaviours
are now allowed only if the user has enough karma to do it.

Here is the new behaviour on courses and slides rating / comment / vote
    -If allow_comment is checked on Course :
        - Review (rating) is allowed on Course only if enough karma
        - Comment is allowed on slides within the course
            only if enough karma and course type is 'training'
        - Vote is allowed on slides within the course
            only if enough karma and course type is 'documentation'
    -If allow_comment is not checked on Course :
        - Review (rating) is not allowed on Course
        - Comment is not allowed on slides within the course
        - Vote is not allowed on slides within the course
    - Rating is not allowed on slides within the course anymore

When a slide is seen by user, it should be marked as completed
(according to its type), and the user completion for the course
is updated. But for public user, we don't want those RPC calls
to be done, as completion for visitor makes no sense.
This commit also hide progressbar when current user is public.

Purpose of this commit is to perform a cleaning and upgrade of the lesson
view in front-end when not using the fullscreen mode. This page had not
been updated since eLearning addition.

A method is added on slide model to have a protected method computing quiz
related information on a given set of slides, notably potential karma gain,
gained karma and number of attempts. It is mainly a code move from controllers
now working in batch.

Some linting is also done, notably a badly-named file.

Purpose
=======

This commit introduces an icon template to factorize some xml code.
It also correctly overrides this template in website_slides_survey to add
the 'certification' case.

Purpose
=======

This commit adds the management and display of uncategorized slides
for both the frontend publishing management and the fullscreen
course views.

We add a "Uncategorized" section on top of all the categories that is
hidden for the student if it's empty.

Course publishers can drag and drop slides from and to that
new "Uncategorized" section to easily reorganize the course.

Purpose
=======

This commit refactors the way slides and categories are reordered in the
frontend course view (training courses). The use of jqueryui's "sortable"
widget makes it easier and more user friendly to drag and drop both sections
and slides to reorganize your course.

Purpose is to ensure more advanced use cases are still supported in new
elearning platform in addition to more public use cases. Fields controlling
access are now

 * enroll: who can enroll on course: public (everyone, simply click on join
   button), invite (added by already members) and payment (in bridge with
   website_sale, if SO with product is confirmed);
 * enroll_group_ids: automatically add members of those groups to the channel
   to ease having groups for a given subset of users;
 * visibility: who can see a channel and its slides: public (everyone, it means
   channel is visible on website for example), members (hidden for non members)
 * website_published on channels and slides; non publishers cannot see what
   is not published, whatever other parameters;
 * upload_group_ids: who can upload on a channel;
 * download_security on a slide is completely removed as it makes no sense
   for most slide types;

To ensure a better user experience responsible of a channel is added in its
members. People uploading a slide are now also allowed to read it to avoid
having inconsistency behavior between upload_group_ids and access rules.

Some tests are added.

Purpose of this commit is to introduce a new way of displaying and managing
slides in eLearning module. Its purpose is to give a better experience to
users when going through a course. Notably a fullscreen mode allows to take
lessons one by one without going out of the elearning display. Integration
of all slide types eases taking the course step by step.

Quiz are introduced in this commit. Those are an addition to slides with
some question / answers (multiple choice). It allows customer to gain karma
and improves gamification. Certifications are still done using the survey
application. Quiz targets only small tests at the end of a given slide.

A new widget is added to display and control slide display in fullscreen
mode. Old display is still available for documentation channels or when
going out of fullscreen mode, to see details on comments / review / statistics
and have access to share options.

Commit linked to task ID 1941250 and PR #31133.

Task #1940360
Subtask of #1902304

Purpose
=======

Adds certification capabilities to the website_slides module.
Channel/courses can now include certifications as a new type of slide.

This new type of slide is available as a "Certification" button on the slide creation
frontend view (next to "Video", "Presentation", ...).
Users have to link the slide to an actual survey that has the 'certificate' field
set to true (that will populate the slide's survey_id field).

Slides of type certification are handled in frontend in a very simple way for now:
- A button "Begin certification" that redirects the user to the related survey frontend.
- A button "Download certification" when the user has succeeded the certification.
- When the survey is done, if it's linked to a slide, a button "Go back to course" allows
  the user to go back to the slide frontend.

(There is a special use case for when the website_publisher designing the survey lands on a
certification slide: he is allowed to test the survey with a survey_input created as test_entry)

Survey creation as well as limited time, limited number of attempts, ... are still completely
handled in the survey module. That means that the user will have to first create a suitable survey
that is a certification and only then create a slide of type "certification" and link
the created survey to it.

Ideally, the taking of the survey should be transparently included in the slide frontend but
it requires a full refactoring of the way surveys are submitted. This will most likely come in
a later commit.

This commit is an advanced merge of full eLearning module (see task #1902304).

Purpose
=======

Website publisher should be allowed to access slides on the frontend even if
he's not a member of the channel.

This commit proposes a new homepage for slides module evolving towards
an eLearning platform. It includes

* a new main page displaying top courses / channels. It displays 3 most
  popular and newest channels as well as its ongoing courses (if logged).
  Achievements and karma update done by eLearning community allow to give
  a gamification look and feel;
* an 'All' page displaying all courses / channels. Tag groups and tags
  allow to search / filter displayed courses;
* a new pimped and revamped display for main course / channel page;

For more details about specifications, send an email to aware people that
will be able to send you mockups. Or see the related task. Thanks to
@qmo-odoo who helped developing this homepage based on its work.

This commit squashes several fixes / light improvements related to the new
slides / elearning homepage [1][2].

Containing notably

 * clean promote strategy field on channel model: less entries as they
   are now used only to display lessons in a given order on channels of
   documentation type;
 * remove promotional fields, not used anymore since partial access on channel
   allowing to have some kind of small preview of slides has been removed;
 * use standard image field (image, image_medium and image_small) and use
   image_resize_image from tools like all other odoo applications;
 * improve image resizing to have medium images better looking on frontend
   and use that nice image_large that broke my build yesterday;
 * add last publication date change on channel;
 * clean dead code;

With this commit, the user can activate review on channel content when
creating a channel from frontend, or editing it from backend. Once
activated, the comment tab below the slide content will allow user
to post a comment with optional rating.
The way of commenting is different regarding channel type:
- documentation: user can post comment and vote (list/dislike) on
slide content
- training: user can post comment with review (rating)

Task-1902304

The idea is a slide can be a HTML page completely customized by
user. So, you can now easily create custom content and publish
it on your website, like a normal slide.

Task-1938643

A slide can now have some external link. For instance, links to
the origin of the document (sources for scientifics papers, ...).
A new model is added to allow the user to provide several link
per slide. Those are display below the channel on website page.

Task-1938643

[IMP] website_slides : use website_profile page template and adds website_slides specific information

Adds slides ands slide.channels specific information (courses) into the website_profile template page.

As there can be more than one slide.channel,the profile page shows everything linked to every slide.channel,
except if the channel_id is given in url arguments.

Adds the 'Go to eLearning' button in the 'new rank reached' mail to encourage the users to continue
to be active on the eLearning platform as well, to gain more karma point and improve there rank.

Task ID : 1922159
PR #30988

Purpose
=======

A slide's 'Embedded views' are reworked as 'Public views' to simplify
the model and be more compliant with the new 'is_preview' field.

The rule is now the following:

A slide is a preview or the view is done as public user (once per session)
-> increment public_views

A slide is viewed as a logged in user that has access to the content
-> increment slide_views
Technically slide_views is a compute of the slide_slide_partner count.

Tests are also added to ensure it is effectively working.

This commit is a sub-part of task ID 1940360 (eLearning integration with
survey) and task ID 1902304 (main eLearning task).

Purpose of this commit is to clean a bit channel model. Promoted slide
feature is removed as people can already choose an order for a given
channel. Moreover promoted slide will not be used when having a eLearning
display of a channel.

Image field on channels is added as it is not depending on promoted slide
anymore.

To simplify future additions a search-specific template is removed to
have a unique template to display a channel content. It will ease future
merge.

This commit is linked to task ID 1936153 and PR #30985.

Purpose of this commit is to add some statistics computation on slide.channel
model. We want notably to have a count of views and votes (likes and dislikes)
on channels. Completion is also computed.

Having stored computed fields for some statistics help achieving that purpose.

Tests are added.

This commit is linked to task ID 1936153 and PR #30985.

As visibility is now mainly based on membership a widget to join channels
is required.
