Separate out IPC::Message::Sender and Channel::Listener into a separate class.

I fixed the places that did IPC::Channel::Sender (I don't even know how this compiled, but I presume this means the "Sender" base class of the "Channel" which ends up being right).

We can fix the other users of this later.
