Gags the given channel temporarily, either until you log out or until
you unmute it. You can still talk on the channel when it is muted but
will not hear anything sent to it. Once a channel is muted, @mutec channel
a second time will unmute it. You can give multiple channels as arguments.
If there are no arguments, the channels you have muted are listed instead.

@mutechannel                         (Lists channels)
@mutechannel monkey pants sandwiches (Toggles the mute status of these three)
