The system completely changed. I also had to adapt classes to new
screen breakpoints.

hidden/hide -> d-none
show -> d-block
hidden-xs -> d-none d-md-(block/inline/...)
hidden-sm -> d-md-none d-lg-(block/inline/...)
hidden-md -> d-lg-none d-xl-(block/inline/...)
hidden-lg -> d-xl-none
visible-xs-* -> d-* d-md-none
visible-sm-* -> d-none d-md-* d-lg-none
visible-md-* -> d-none d-lg-* d-xl-none
visible-lg-* -> d-none d-xl-*
hidden-print -> d-print-none
visible-print-* -> d-none d-print-*
...
and all possible combination of those had to be handled too.

Today, Odoo is really tricky to use without seeing the screen, it must be improved to be usable.

This PR forbid to use labels without a "for" attribute, add some title, rule and aria attributes in HTML. With that, Odoo will be fully usable with a screen reader.

This commit introduce a full redesign of all JS views.  We started
basically from scratch.  The goal was to unify all the various views
under a common framework, to make them testable, to make then usable in
different conditions (in studio, or in the frontend), and to make our
lives easier.

Some important points are:
- we introduced new coding guidelines (camelCase, 80 chars width, ...)
- we have a brand new testing framework (still QUnit based)
- kanban view moved to the web addon
- calendar view (formerly web_calender) moved to web as well
- the tree view was removed
- all new code should be documented

We hope that this code is the start of a new era for the Odoo web
client, we want to have a high quality codebase, well documented, well
tested, well designed.

Work done by the framework team: mostly aab, ged, chm, dmo, qsm

Because the configuration of pad is moved in general settings.

replace the icon for fullscreen by the same one used on YouTube (or a similar one) + add tooltip 'Full Screen' and 'Exit Full Screen'
