Geiger Counter - Almost Final!

All that's left to do is move the code over to one microcontroller (it's currently running on 3, sorta, one for the PWM waveform that drives the boost driver, one that runs the mock LCD code (the one on the breadboard), and the PolyBot board, where the real code is running right now (the one that makes the speaker click and *should* be displaying CPM and mR/H, but that part is broken at the moment)), write the function to display an integer to the LCD, and just do some general cleanup and testing of other components.

The geiger counter (excluding PolyBot, that separate board on the left) is now running on 3 NiMH coin cells charged by a crank, that I took out of a cheap flashlight. The current consumption ranges from 30-40mA (about the minimum where the LCD still works) down to 300uA (when it's only the pure geiger counter/clicking that works).
