* Remove recursive assets inclusions (i.e. assets_editor was including
assets_common, summernote, ...)
* Better construct the assets (link, then script + type attribute)
* Better include the assets (split js / css, always use t-call-assets)
* Simplifies the number of assets
* Move bootstrap js to assets common
* assets_frontend is now created by web module to allow using it on the
connexion page but also in the web_editor, where colors have to be
bootstrap/theme ones. Note: if a module depends on website, then keep
using the inherit_id="WEBSITE.assets_frontend"
The original commit by fka used to define less variables like this:
@px-4: 4px
@px-8: 8px
The goal was to be able to change the margin values in
media queries for smaller screens.
However, as the less is only compiled once in css, those
variables didn't really help as you couldn't redefine them
from inside a media query and have the less magically
reassign the margins on the fly.
I created less helper functions to be able to easily redefine
the margins for smaller screens from inside media queries.
The task also required to replace the nbsp in the html by the
newly created mr and ml classes.
This is also the first phase of the sass -> less transition.
