Purpose
=======
This commit rework the design of the Kanban view of the mailing list.
There are now 2 styles for this Kanban view
- Grouped, for this one we keep the same "card design" as before
- Ungrouped, we use a "list style" view, and the card take the all
width of the screen
Add some actions to be able to import quickly contacts from this view
or to send a mailing to the mailing contact list.
