e4f638a17a Add Bank Selection to Debug Monitor 
- The debug monitor will not display the current bank id in the prompt
- The debug monitor has a new command to set the current bank for the lower 32K
NOTE: Bank selection is not possible when running under interrupt mode 1.  The command will be rejected with an error.

e60bf088c9 DSKY Disk Activity Cleanup 
- The DSKY(ng) can display disk I/O activity as the system runs.  This capability was implemented very erratically.  This update overhauls the mechanism, makes it consistent, and implements it across all disk drivers.
