send method. Even though it delegates to a method that
will wait for being connected, send(channel, msg) can't
properly do its channel verification until the connection
is fully setup. So now it waits.
I also went ahead and added constants for the normal default
(previouslly hidden) channels that are used during normal
send(msg). Useful for code that wants to deal with channels
genericly but still wants to be able to use the default
channels.
