Lowered gains to try and reduce noise.  Also merged in some logic from
main that was handling multiple 'z' requests.
Fixed a major bug with the frequency of the ADC reading.
Made a change that after some testing I think will drastically improve
the reliability of the PIC writing its XBee address to memory.
Merge branch 'tmp'
