cb47d23233 Fixed issue with colour 0 being the mask colour 
For systems that legitimately use 0 for black, this causes a
problem, so I instead use 0xFFFFFFFF for the mask colour which
corresponds to transparent white in ARGB format, which minifb
doesn't support anyways

f601290771 Fixed bug in MOVEM and added tests for it 
It was previously decrementing addresses if the direction was from
registers to memory, but that's incorrect.  It should increment the
address always when using an addressing mode other than the ARecDec
mode.  I also added a memory location to the test cases to test the
MOVEM instruction by comparing what memory was read/written (but it's
only one u32 because that's the minimum we need)

b6cccea437 Added read only memory and debugger numbered continuations 
There is also a breakpoint error, so that if a read-only memory
location is written to, it will escape to the debugger rather than
exiting the program.

93c080eae6 Fixed interrupts 
Previously the m68k wasn't masking interrupts with an equal priorty.
I also modified how they work, such that the cpus will check the
controller rather than wait for the notification call
