Fixed Potential Bug

Fixed potential bug where ADC has been disabled after being powered down.

Reduced Power Consumption

Use ADCSRA &= ~(1 << ADEN); to properly disable the ADC,
this reduces the Power-Down sleep mode power consumption
from 100µA to 10µA.

First Release

Code complete, no known bugs, polished user interface.
