[arm-allstar] Temperature Based Fan Script

[Mike Besemer]

Has anyone written a fan control script based on CPU temperature?  Ideally,
I'd like to have a script that could monitor the CPU temperature and run the
fan when the CPU exceeds a certain (user setable)  setpoint.  

I saw the script that Doug wrote to control the fan based on PTT but one of
my Pi's needs intermittent cooling to keep the CPU below 50C regardless of
PTT activity.
