Added disablePwmPin()
.
- Calls
digitalWrite()
to call core functionturnOffPWM()
- Extra code for ATmega328P/168 to implement turning PWM off on toggle-only pins
- Extra code for LGT8F328P to PWM off toggle-only pins and switch Timer3 pins back from port F to port D (which share pins on SSOP20 and FPQ32)
ATtiny's and ATmega8A were not tested yet, so no special code for toggle pins on those.
