Group support

[dkvdm]

Hey, I got my Hue today and I simply love the clean implementation of this client. It's great, but it's missing group support like phue does. I'm not a python genius and I haven't been able to convert the archaic httplib requests to the new requests lib. Care to help out?

Thanks!
Dennis

Very neat. I was unaware that somebody had reversed groups. I'll take a look at it next time I get a chance.
