PURPOSE
Allow quick message creation by allowing create multi on mail.message.
Also introduce a new helper tool method to log in batch on records.
SPECIFICATIONS
Purpose of this commit is to add a way to log notes in batch on a document.
Those notes are logged without any notification mechanism, allowing to
attach a note in as few queries as possible.
This is implemented by
* allowing create multi on mail.message. Nothing changes in its behavior
except that it is not working on a list of dictionaries;
* adding a ``_message_log_batch`` tool method allowing to post a batch
of notes on records;
* adding a tool method to correctly find author / email_from, to be used
in various message_post / log / notify methods in order to have the
same behavior in all those methods;
Logging in batch will soon be used in SMS when attaching a note to sent
SMS without having extra notifications. This will be used notably when
performing mass SMS without using the standard notification mechanism.
