Binding for Philips TVs with jointspace API

I created a binding for my Philips TV into openhab. All their models (since 2011) support a json-based api called jointSPACE (see http://jointspace.sourceforge.net/projectdata/documentation/jasonApi/index.html for the reference what one can do with it) that allows controlling some functionality over ethernet.

Right now the binding can:
- Send Button commands
- Sets and Read Volume/Mute
- Set and Get Colors of Ambilight "Pixels"
