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.
