25KHz PWM Fan Controller

[kni]

Hi All,
I finished another Moteino project over the weekend.

This one was fairly straightforward. It modifies timer2 for 25KHz operation then sets a duty cycle, based on a linear relationship with the temperature. The Low and High temperature setpoint values are stored in eeprom. They are configurable from the Moteino Gateway UI.
