Added Web UI controls and view in status
Added power up behaviour (nothing, close, open, last position)
Added curtain style (Roller, etc...) for UI status and to be used in MQTT
This will add support for the KingArt Wifi Curtain Switch. There are no buttons in the web interface as I could not figure out how to create them (any help on that is welcome).
For now the switch can be controlled over MQTT:
"{hostname}/curtain/set"
"{hostname}/curtain"
