Creates a name for a channel. The name will propagate across
your botnet (if you're hooked into one) and can be used instead of the channel # when
changing chat channels (see .chat).
If you omit the channel # and name, it will just dump a list of the current named
channels.
assoc <*channel #> <name>
Creates a name for a local channel. These channels are local
to the bot itself.
assoc <[*]channel #>
Wipes out the name for a channel, if there was one.
