Unsubscribe to channels with wild card

[shaharmintz]

If I'm correct, the current code doesn't allow unsubscribing to channels with wild cards,
i.e if I have 2 channels such as: rooms/parties/1 and rooms/parties/2, calling unsubscribe_to("rooms/parties/") [notice the ''] would remove subscription of both channels.
I'd love to know if this is actually currently possible, if not - requesting as enhancement.
