Kick MUC participant when shutting down service
Currently, when biboumi is shut down, it will send a presence-unavailable to the transport-joined clients:
<presence to="full@jid" from="#email@example.com" type="unavailable"> <status>Closing Link: ("Gateway shutdown")</status> <x xmlns="http://jabber.org/protocol/muc#user"><status code="110"/></x> </presence>
Please add a
<status code="307"/> to indicate that the user has been forcibly removed from the channel.
This surely is in a grey area of the XEP, but there are client( librarie)s that fail to process the above presence *cough* smack *cough*.
