Hunter Douglas shade plugin version 1.12.4

Some debug for my G2 friends in the last two versions.  Had to do with polling & with a left/right shade which has a very unique JSON coming from the gateway.

Other than that, it's been quiet out there so I assume everyone is happy.  

I personally have this plugin in constant use with 14 shades and about 20 scenes.  My programs are written to during the day move them around using scenes.  Scheduling of those move is done in my programs & updated from UD Mobile.  When I manually move a shade I usually use the HunterDouglas Powerview app, or in room remote.

This plugin has my use case covered, so I do not have any feature map in the works.  I am open to good ideas from the user base, but if none come along then I am in really in debug mode when/if they come along.  Let me know.
