[IMP] im_livechat : adds some design improvements in form and list views

More and more people are using the Live Chat and complaining about it
because it's not user friendly. This commit modifies a bit the design
of the form and list view without changing the functionnality

Improves im_livechat.channel kanban cards

Improves the channel form view:
Introduce tabs to manage the different aspect of the channel :
Operators, Options, Widget, Rules

Improves the session tree view:
Sort by date desc, adds the number of messages per session
and replace the rating last value by his corresponding icon.

Improves livechat session form view:
Introduce a kanban view that list all the messages of the session

Improves livechat session rating view:
For congruence inside the module, renaming 'Resource' group By filter
into 'Code' as the rating resource_name in this case is the same as
the session code. So we use the same terms in this view and in reports
