With the new views, we totally broke the dashboard. This commit
rewrites all the code to comply with our new coding guidelines, and make
sure it works, with some tests.
Note that a big change is that we don't instantiate an action manager
and a view manager, we directly instantiate the views.
Also, this is not the best way to organize the dashboard. I think that
it should be a client action, not a form view, so we don't have to
overload all the form view classes and we don't depend on form view
behaviour/view caches/...
