[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.
