Hunter Douglas shade plugin version 0.0.5

Still more to do here but we have nodes for shades and scenes.  The ability to activate scenes.  

Can open / close / stop or tilt open / close shades.

Going forward I am looking to clean up parameters which do not belong with certain types of shades, as well as add the ability to move shades to specific locations.

Open to feedback and / or requests.
