Thibault Delavallée 0408f7931f [IMP] mail: compose options for mass mailing
Composer in mass mailing mode currently keeps a copy of the emails in the
document communication history (chatter). It is done by keeping the
mail_message that is used to create the mail_mail record. It is now possible
to customize this behavior. Using auto_delete_message one can choose to not
keep a copy of the sent emails.

Note that the notification field on the mail_mail is used to know if the
associated mail_message has to be unlinked when unlinking the mail_mail.

Auto deletion of sent emails is based on the option on the template used
to generate the emails. It is now possible to bypass the template behavior
if requested, using the auto_delete field in the composer. If this field
is not set, the previous behavior applies.

It is now also possible to tune the message_type and subtype_id of the
posted message. Previously all messages posted through the composer
were comments with a computed subtype being either a comment or a note.
Those values are now default values but can be changed in the wizard
and correctly taken into account when posting the message.

Those modification do not change anything in the default behavior of the
composer and templates. They are mainly introduced for use in future
improvements in various addons, like sending reminder emails that are
not stored.
