V0.6 Changed HUEPI object notation from literal to protoype notation and CTtoRGB for models not supporting CT

Changed HUEPI object notation from literal to protoype notation to make a bigger difference between static helper methods and object interface
Group- and Light-SetColortemperature are set via SetCT now
Added HUEPI.HelperCTtoRGB to Allow ColorLights to be set with CT as RGB
GroupSetCT splits group into Light and calls LightSetCT per Light
LightSetCT looks up lamp Model and sets either CT or RGB based on Model
Note: Using Lightstate objects are not CT to RGB converted
PortalBridges[] is renamed to LocalBridges[]
