Implement fake QUIT handling via a NOTICE when doing a replay.

Since user QUIT messages don't contain channel names, clients that didn't know which channels a nick was in when receiving a quit message for that nick can't show a per-channel QUIT notification.
Some clients just display the QUIT message in the server status window, others silently ignore it.
Cater for those clients by sending a NOTICE about the QUIT rather than replaying it - assuming the nick isn't still in any of our channels.
