Added dummy light driver. Now skywebsense likes Z1
The light sensor driver is mapped to the same pin as the potentiometer in Z1 Starter Platform. sky-websense is untouched, though.

* The Photosynthetically Active Radiation (PAR) sensor as well as the

*

* VsensorTSR = ADCValueTSR/4096 * Vref (1b)
|
||||
* where Vref = 2.5V
|
||||
*
|
||||
* This voltage creates a current through a resistor R=100KOhm and this
|
||||
* current has a linear relationship with the light intensity in Lux.
