I believe this adds registry support. The UI allows me to change
the entity ID now.
For example, a light bulb called "BasementHallLight" in the Vera
has an initial Entity ID like light.basementhalllight_108, where
108 is the unique ID that the Vera assigned the device when I
added it to the z-wave network.
Now I can use the UI to change the Entity ID to
light.basementhalllight and I can still turn it on and off.
