[IMP] mail.message: can now have void subjects. Void subjects are not displayed in chatter/wall; this allows to have a more flexible way to display blog post, while avoiding to display unnecessary data for notifications or quick replies. This imply that a way to manually add a subject when posting a comment is required; this will be done in openchatter part3.
