PURPOSE
Purpose of this commit is to add options and improve sms composer behavior.
Followup of merge 4287481bf0 .
SPECIFICATIONS
* mass mode: add an option to keep archives when doing mass sms. This mode
is actually a _message_sms in batch using the note subtype to speedup the
process;
* improve _message_sms_schedule_mass to allow more fine-tuning of options
when calling it;
* do not block sending SMS in batch if some recipients are invalid. Indeed
using notifications there will be traces of failed SMS;
* avoid reload of form view;
