Since the fullscreen widget has been revamped, it needed
to be pixel perfect. This commit cleans the CSS and DOM
structure in order to optimize and sublime it.

Task-1941250

This commit makes the 'Fullscreen' page a complete odoo
widgets. We decided to split it into some sub widget:
- Fullscreen: will be the master piece, handle communication of
components, displaying slide content, setting slide as completed,
handling server RPC calls, ....
- Sidebar: responsible for slide navigation, based on the table of
content. (prev, next, keyboard naviguation, ...)
- VideoPlayer: display content for Youtube video and handling player
event to auto set as completed, ...

The DOM of this page is still rendered serverside. DOM was cleaned in
order to be less complex and less deep. CSS style was also reviewed
to decrease line of code.

Fullscreen is now completely using Quiz widget with events triggered.

Task-1942852

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.

See original eLearning task for main specifications [1].

This commit makes the quiz widget a real odoo widget that triggers up some
events. The widget is now only responsible of

 * fetching quiz data (if not given)
 * decorating the anwsers according to the result
 * displaying message (error or modal)

To do so, some code move/rewrite was needed

 * extract and factorize some template
 * add 'sudo' on technical model to avoid access rights error
 * factorize some python method from controller to model
 * remove some CSS classes to lighten the code
 * fixing access model error
 * make quiz widget handle the display of error message
 * give browse record for template rendering, rather than slug
 * cleaning some spaghetti code in Fullscreen widget
 * ...
