Fix ADF bugs ... including still driving the needle when power off.

Browse source 
ADF bug fixes from John Denker.  Changes from current behaviour are:
* Include the power button in the electrical checks
* Raise the required input voltage from 1V to 8V
* Don't reset the heading to 90 degrees when out of range or no power
  (heading is now only reset to 90 in ANT or TEST mode)
