Revamped the opcode table, made the emulator more
efficient, and ported SuBEditor to C. I revamped the opcode table to add another prefix bit for the addressing mode, finally giving access to all addresses, without wasting any bytes. I made the stack based operations more efficient, by sort of applying Duff's device to it. And I ported SuBEditor to C, to make it easier for me to figure out how to implement SuBAsm.
