Allow binding an optional `action_id` to filters.
The web client will try to identify the specific
action ID when saving new filters. If no contextual
action exists, the filter is saved globally for
the model.
This will automatically keep filters within their
original menu when there are several menus/actions
leading to a given list of documents.
In some cases the action_id will not match the
filter model, which should be fine (e.g. when opening
a many2one completion popup for model `foo` within
a menu of model `bar`).
It is also still be possible to have a filter apply
to all actions/menus for a given model by manually
deleting the action_id value in the filter
(e.g. via the Manage Filters debug menu).
When updating a filter the action_id value is ignored
so that old global filters will be gradually replaced
by new "local" filters.
Also added an _order to ensure stable ordering of the
filters.
[MERGP] Inline Searchview
This task split the searchview in two parts: SearchView and SearchViewDrawer. The drawer is displayed inside the main view and the searchview stays in place. It also changes the scrolling behavior of the web client: the main view area can scroll without affecting the UI (so the various menus stays in place)
Because of this, other large changes have been made:
the drawer has been redesigned,
the Custom Filter widget has been split in two (Custom Report and SaveCurrentFilter),
the main view is now scrollable, so the UI stays in place and only the view can change
The text 'Group By...' has been changed into 'Group By' (most addons had to be modified)
bootstrap classes are used when it makes sense (for example, badge)
the left menu is also scrollable (separately from the main view)
It is likely that some stupid bugs have been introduced. Please don't hurt me.
