Url saved need to be relative.
Before this commit, demo was relative, but once updated, urls was absolute.

 * Correct some language
 * Add extra steps to redirect to the implementation planner after having
  finished the tour

Don't refresh page between each validation.

Apps store uses comma separated convention to sort by author the apps.
Closes #13574

Hide fields if not in debug mode.

This enables extensions of `ir.model` and `ir.model.fields` with computed
fields without messing up too much with reflection itself.

If those events are catched by the web_client, it means that no other widget
did handle them, so simply call their on_fail callback.

The `model` has been added to the name_get.

A non stored, computed field 'reference' is added to ir.model.data, this
allows the form view to display a nice link to open the record in form
view.

The combinaison of `web_icon` and `web_icon_data` is used
to determine if the menu has:
 * no icon
 * an image icon: [module, path]
 * a built icon: [icon_class, icon_color, background_color]

Possibility to inherit _check_group to have groups in attribute
In studio, we need to avoid to delete groups node

The commit e59a7fe3 has moved
the ACE editor from website to web_editor. As some code on ir_ui_view
was used for this widget, the code has also been moved to web_editor.

The iframe is set in a template inside a div.
The widget is returned so it can be extended.

Ace editor is not very smart, it does a rpc for each inherited view, it
tries to load workers before deciding not to use them, and it does way
too much work in general.  This commits tries to make sure that only the
necessary rpcs are done (lazily).

This comportement was added in the DebugManager to trigger an event.
As this event could be useful in other situations (e.g. studio), we trigger
the event directly in the ActionManager. By default, the WebClient does not
use this event but an handler is added to be overwritten.

This handler is overwritten in some widgets (DebugManager, Studio, etc.) that
requires the Systray items instances so we add them in ´widgets´ in the Systray Menu.

As the module dashboard uses multiple ActionManager, the event bubbling should be
avoided in this case.

A refactoring of the js views is in progress.  Those new views are used
in web studio, and this change is part of it. This is necessary to allow
web studio to correctly fetch data from the server when rendering a
preview.  Note: this is necessary for special widgets (status bar,
selection, radio widgets)

Sometimes, we need better control on the cache.  For example, if a view or an
action has been changed, it is required to make sure that the correct
data is loaded.

Sort systray items by sequence to allow, e.g. to force the planner item to
be the left-most item of the systray as it is not displayed in all apps, and
thus produces a flickering of the other items.

Also invert the push order of the two mail items to keep the previous order
as they are now prepended instead of appended.

The previous report was a workaround to avoid changing the model in the stable
version using a custom widget.
Replace by a proper wizard.

Website access rights were buggy. The editor assets and website editor
assets have to be loaded together to work so the previous behavior
which only loaded one with the restricted access right was not right.
Also, people which had the "Manager" access right for model like event
or job only got access to creation and edition of those objects if they
had the full access to website access rights.

Now the website module creates the two same groups :
* group_website_publisher: load all editor assets, give access to
page creation for model the user has access (event, job, ...) and
edition of those pages
* group_website_designer: implies the first one and give access in
creation and edition of all pages + access of all website menus

The manager access rights for event, product, jobs, etc now implies
the group_website_publisher group for the user (so that the manager
have the editor assets and editor ui).
Note: some python codes use the group_website_publisher for no right
reason, this has to be adapted.

This picture is used in python code and not in description.

The previous line was O(n^2). With n=1200 like we just have now,
things didn't look good for this loop and confirming an attendee
registration to such event took approx. 13 seconds.

Since the list comprehension is in no mean linked to the value
of "item" in the filter, I simply moved it out so it is only
computed once.

For historical reasons, `vobject`* Python library is not mandatory in
Odoo.

Since refactoring 6af6148a,
get_ics_file() returns now a dictionary whose keys are calendar.event
ids and values are the corresponding ics file.
If `vobject` is not available, it returns an empty dictionary that
could cause calendar.py to crash because it always expects to find the
event's key.

Before this refactoring, this method was called and architectured in a
different manner, so no crash was happening.

This commit prevents the crash if `vobject` is not installed and logs a
warning.

*vobject allows to generate iCalendar files

There was no bug but now the behaviors are more consistent :

- Demo data now declare a black invisible filter instead of nothing.
This allows user to see the effect of filter intensity option
(otherwise it had no visible effect since there was no filter color).

- If the filter intensity is set to "None" (invisible filter) and that
a filter color option is highlighted or chosen, a "Low" filter
intensity is automatically highlighted or chosen so that the user see
the filter color he is chosing (instead of having to choose the filter
intensity first).

- Hide the "Size" option on the blog list page since it has not visible
effect there.

- Some code "performance" improvements in option selection.
