np2active_step_over(): Skip INTs
np2break_memory_write_naive(): Check for null pointer

Fixes a crash when resetting the emulation.
viewpaint_print_addr(): Change off parameter to UINT32

That took me a while to notice that the view1mb addresses were cut off after 0xffff... -.-
Only call viewstat_update() on ViewClientProc():WM_PAINT
Move mode-specific reload handling away from viewer_allreload()
Fix memory search wrapping to work correctly in segmented modes

... as well as the embarrassing confusion when hitting the Cancel button in the search dialog -.-
Ensure that every mode switching permutation updates the display as expected

This was driving me mad, too.
