Adapt the Favorites menu so that addons appending stuff in it are compliant with
the enterprise edition.
Mainly, creation of dashboard.less from of dashboard.sass so that we can use mixins
defined in the web addon.
Some changes as well in the dashboard view to make it compliant with the enterprise
edition.
Use correct naming convention: classnames with underscores, less mixins with hyphens.
