IMP:
- mail.compose.message: added a context key 'mail_post_autofollow' that automatically subscribe the message recipients to the document followers, if any
- sale, purchase, invoice: recipients of 'Send by email' action are now automatically added as followers, using the above key
- mail: the Chatter widget on documents now sets the displayed messages as read
- mail: for incoming emails going through message_process that have an author, the author is added in the related document followers, if any
FIX:
- mail: attachments added in Chatter/Mailboxes were not added to the notifications emails send to followers/recipients
- portal: fixed various mail_mail created without specifying the type field, that could crash if a conflicting 'default_type' key was present in context (i.e. in opportunities)
