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"

* rfbridge: fix names and ordering

* build rfbridge

* ADC_VCC is not macro

* In esp.h ADC_VCC and ADC_TOUT is not macro, so define macro.

* ADC_VCC and ADC_TOUT fixes in utils.ino and sensors.h

* Adding support for I2C temperature and humidity sensor HDC1080 / 831R

* Added HDC1080 to test\build\sensor.h and arduino.h

* added brackets

* Revert ADC_MODE_VALUE to initial values

* Eof newline

* Eof newline
