Updated the bridge to handle a new dimming and value control context,

$intensity.mat{(X*1)} for custom calculations. Also, added helpers for
generating URLS on the value contexts.

Alternatively the Bridge supports custom calls as well. The Bridge handles basic commands such as "On", "Off" and "brightness" commands of the hue protocol.
