+ Fix EasyMini voltage displays. Early EasyMini prototypes
+ used a 3.0V regulator, and AltosUI still used that value as
+ the basis of the computation. Production EasyMini boards
+ have always shipped with a 3.3V regulator. Also, purple
+ EasyMini boards sensed the battery voltage past the blocking
+ diode, resulting in a drop of about 150mV from the true
+ battery voltage. Compensate for that when displaying the
+ value.
