Fibaro HC3 Update - Scenes and Device API Builder

Change to the scenes and device URL builders for the updated HC3 API.

Note that Devices now use POST and require application/json body.

For turnOn/turnOff: {"args": []}
For Dimmer Percentage: {"args":[${intensity.percent}]}

Scenes can continue to use GET. POST is optional and requires a json body.
