for channel-related stuff. mail.channel views as well as timeline views
and actions have been renamed. Now the names follow the guidelines and
will be used in the upcoming refactoring of mail and chat.
model has been renamed to mail.channel to prepare the slack modeling.
In future commits the mail.group model will be merged with the channel
model from im_chat. The first move is to rename mail.group into
mail.channel to have a model that will unite both features.
1. The merge of the "email_template" module into the "mail" module.
2. The send action of the mass mailing has been moved from the frontend to a cron, because it was too slow to send over 10,000 mails (the user's browser was blocked for 15 - 20 minutes). Mass mailings have now their own process in the kanban view.
3. Mails sent from the mail form are sent immediatly instead of from the mail queue (for instance, when you go to sales > customers > list view > select 2 -3 customers > More > Partner Mass Mailing).
4. Users have now the choice from which mailing list they want to unsubscribe when they click on the unsubscribe link at the bottom of the mail.
5. Mass mailings inherit from their campaign UTMs and mass mailing campaigns are linked to an UTM campaign.
6. Many little improvements
