This fixes a bug where an unauthed IRC connection will cause your
clients nick to be the default nick. But this is before we update
the client to use this nick. If a client tried another nick when
connecting then they are still expecting this nick.
UpdateModule has been moved to CZNC because it doesn't really fit into
CUser. The new UpdateModule will reload the module for global modules,
user modules and network modules.
Fixes#69
The result of CIRCNetwork::IsUserOnline() will only show clients which
do not have the away state set. This value is not set from the IRC
command AWAY, but a future module could use this behaviour.
Some CIRCNetwork::IsUserAttached() checks are now moved into of
CIRCNetwork::IsUserOnline() checks.
This allows "away" clients to store buffer even if KeepBuffer is false.
