Added a method to QueueManager to let subclasses do stuff when idle. Needed so that XMPP queue manager can service its message queue. Cleaned up jabber_broadcast_message quite a bit. Use custom joins instead of loop-and-query, should fix some problems with users who are getting messages even after turning off notification. Only build $msg and $entry once, and use the XMPPHP function for messages with a payload, rather than rolling our own. darcs-hash:20080829200352-84dde-427e4ca8c81d4222a36f78e7c580b611ff0bf765.gz
