Finally handling key presses in the console! (Took long enough, huh?) Added a dead simple console echo example program in 6502 assembly, as well.

Checkpoint of my Swing UI refactoring. Usable for output-only programs, but only barely.

Simulator is just about ready for real-world testing now. Added a simulated MOS6551 ACIA at address $C000 which does buffered input and output via the console. Updated the README with a bit more documentation, and bumped the version number to 0.1 because I'm impatient.

- Major overhaul of the Simulator control class (where 'main' lives). - Removed the CommandParser class entirely, as the weird dependency between Simulator and CommandParser never made me comfortable. - Added a Command inner class to Simulator that handles some of the command line tokenizing.

Playing around with the command parser and the Simulator class. Safe to ignore.

- Updated Cobertura Maven plugin to version 2.3 (threadsafe) - Finished refactor of instruction argument address decoding. Much DRYer now (but could still be DRYer yet).
