PCR code fixes

Changed recipe (times and temperatures) to match MTWASP from openPCR
Added +2 degrees to offset temperature differences from sensed
temperature in well vs temperature read by thermistors
Fix serial print - now includes cycle number
Measured rise and fall time and included in calcRemainingTime()
Changed fudgeFactor to smaller value since rise and fall time are now
included
Eagle CAD fixes

Changed 10k resistor attached to thermistor voltage divider network to
1k (1k provides broadest range for ADC on atmega328p)
