[IMP] sms: allow to send SMS to oneself
[IMP] sms: allow to send SMS to oneself

Currently discuss post (through mail or sms) does not allow the author
to be notified of its content, as

  * he posted it and is therefore already updated;
  * it could create email loops;

However with SMS one could easily try to send SMS to himself using the
sms composer that is different from the mail composer. In that case
just use the ``mail_notify_author`` context key allowing to bypass the
"no author notification" rule.
