SCP: Extended EXPECT and SEND to have more flexible activation delays

Browse Source 
- EXPECT will now tolerate a HALTAFTER=n parameter which delay the simulator stopping execution for n instructions.  Unpredictable behavior will happen if multiple EXPECT conditions see matching data before the first actualy halt occurs.
- SEND has an AFTER=n argument which delays the initial stuffed data from being input for at least n instructions.  It also has a DELAY=m argument which specifies the minimum number of instructions which must execute between stuffed input data.
- Changed run_cmd() to no longer clear pending breakpoint actions before starting instruction execution.
- Added a -Q switch to the commands which dispatch through run_cmd() (RUN, STEP, NEXT, GO, BOOT, etc.).  This switch will suppress status output when execution stops.  This will allow sequences of breakpoint action commands to silently execute when needed.
