[FIX] bus, im_chat, im_livechat : use correct session to rpc call, little refactoring of im_livechat js, and prepare js code for Odoo Support.
[FIX] base_gengo, website_gengo: groups on the gengo key.

Basically the admin group can read the gengo key. When adding website_gengo that adds the
website groups, the groups allowed to access the key are updated.

This is done because in base_gengo the website groups are not necesssarily defined. Website
is not a dependency of base_gengo.

[FIX] event: avoid double "Publish" button

The event.track view wa sextending the event.event view which was adding action buttons linked to the event.event object instead of the track.
This patch uses the general website view to avoid the confusion (and the risk of publishing an event instead a track).
[FIX] product: Put product_variant_count on template form view.

Was missing to be used in domain added at 92d8f15.
