Adds glycol support via Beer probe. DO NOT run the Glycol build against a standard compressor setup (refrigerator.) This is only for glycol control. The RevC and I2C shields are for the standard builds and have not changed since 0.2.12.
The Glycol variant uses the I2C pinouts and must use A0 as the OneWire pin.
