Subscribing to multiple channels doesn't appear to produce any output #4

Are they expected to work yet? I tried adding multiple channels to my subscription and it doesn't seem to give me any output. Just subscribing to one at a time works fine.

Ah, I see the issue, if you are subscribe to multiple channels it return: [[a], Timestamp, Channelname]

Will have to do a few changes to make that work well, like will need to also always pass the channel name of the received message to the onMsg function.

Is it even worth supporting that directly, instead of just issuing separate calls to subscribe with different handlers? I just figured that since it took a list it was directly supported, but I don't see much benefit in complicating the callback mechanism when we can just include that information in the closure passed by the user.
