swipe to flip through channels

[jane]

Swipe to flip through channels instead of having to go back to the Colloquies tab.

2nd this request!

This would be absolutely awesome.

I'm sure there's probably a limit to how many channels you could do this with, but maybe if there's more than 16 channels (or whatever), swiping is disabled. In this case you could still use the current method for switching between channels.

This would perhaps also be useful on multi touch Macs. I'll try.
