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.

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

Added BusPort to more accurately emulate the bus requests of the 68k
...
The BusPort is created before the CPU and is passed to it. It can
have an offset, limit the address sizes, and break up bus request
beyond a certain number of bytes into multiple requests

Fixed a bug in bit field instruction decode
...
We were trying to decode the effective address before fetching the
second instruction word for bitfield instructions, which was causing
it to use the wrong word for the offset:width information, which was
preventing the shell from printing to the screen after boot
