Michael Bruck:

- Added simulate_reset_on_next_halt that can be extended to do all sorts
of cleanups for systems without proper reset. Right now it just writes 0
to the control register to disable caches.
- Step skips over Wait for Interrupt instruction
- fix for count
- fix for printf format errors
