Add support for attiny84a

Browse source 
Attiny84a requires two things:
-Support for rewriting the avrdude mcu to attiny84 even if the gcc mmcu parameter stays as attiny84a
-Removal of the avrdude -D flag. Without this, no uploaded sketch would ever take on the attiny84a (determined by experimentation and comparison of parameters with the arduino ide)
