SDS: Allow specifying breakpoints as being in monitor, user or normal mode only

Browse Source 
Breakpoint logic now allows four execution-type breakpoints:
 -E  as before, break if PC equals address, unqualified by mode
 -M break if PC equals address and machine is in monitor mode
 -N break if PC equals address and machine is in normal (SDS 930) mode
 -U break if PC equals address and machine is in user mode
