Bug 19955: Add ability to process only one 'type' of message ( sms, email, etc ) for a given run of process_message_queue.pl
It would be nice to allow emails to be sent overnight, but limit the sending of SMS messages to hours when people are awake. Adding a type limit to process_message_queue.pl would allow this to be accomplished easily.
