XMPP queued output & initial retooling of DB queue manager to support non-Notice objects.

This avoids problems with multiple connected resources: * multiple windows shown in some chat clients (psi, gajim, kopete) * extra load on server * incoming message delivery forwarding issues Database changes: * queue_item drops 'notice_id' in favor of a 'frame' blob. This is based on Craig Andrews' work branch to generalize queues to take any object, but conservatively leaving out the serialization for now.
