mod_muc_rtbl: also filter messages
This was a bit tricky because we don't want to run the JIDs
through SHA256 on each message. Took a while to come up with this
simple plan of just caching the SHA256 of the JIDs on the
occupants.
This will leave some dirt in the occupants after unloading the
module, but that should be ok; once they cycle the room, the
hashes will be gone.
This is direly needed, otherwise, there is a tight race between
the moderation activities and the actors joining the room.
