[MERGE] web,*: list view improvements

This branch brings several improvements related to the list view:

- grouped list views are now editable
- 'expand' attribute can be used to open by default the first level groups
- if there are a lot of groups, a pager is displayed (instead of having all
groups in the same page)
- when grouped on a many2one field, custom buttons (on the many2one
comodel) can be inserted in each group's header
- we can edit several records in a row in editable list views
- editable lists do not flicker anymore when switching a row to edit mode
- we can navigate through the cells in list views with the arrows (in
readonly)
