Pulled the 6502 into a CPU namespace, making it an instance of something that has micro-opcodes and schedules them, and factoring out the formulation of a register pair.

Switched the 6560 to two bytes per pixel, since one isn't sufficient for precision and because mixing up the implementation might help me to figure out what's amiss.
