Admar Schoonen 9e158c13fd Rough parameter tuning + reduced flickering 
* rough parameter tuning for TEPT4400 light sensor
* reduced flickering at low brightness values by reducing number of brightness

Admar Schoonen ff698171aa Implemented dimming based on amount of ambient light. 
Requires a phototranistor (TEPT4400) and series resistor (I used 2.2 kOhm) on
ADC0 (pin 23). Range is quite limited though, so will probably need to modify
hardware a bit and do some more software tuning.
