Subject: [PATCH] Handle channel user modes 'a', 'h', and 'q' from remote
 servers

These channel user modes aren't used for anything at the moment, but
ngIRCd knows that these three modes are "channel user modes" and not
"channel modes", that is that these modes take an "nick name" argument.

Like unknown user and channel modes, these modes are saved and forwarded,
but ignored otherwise.
