Got real hardware blink monitoring working!
Improved sensor code - use poweroff/poweron, etc.
Totally rewrote detection algorithm.

Direct sunlight made the other one useless. This one should work in
direct sunlight and all other conditions as well.

I also made the TSL class more of an actual object, not just a container
for constants.
