Loading with Card Load Select does not work

Attempting to boot the system using Card Load Select does not work in the 
B5500Console.html UI. It does work using SyllableDebugger, however.

Fixed in release 0.14. The problem was that IOUnit.initiateLoad() was using 
IOUnit.finish() to construct the result descriptor and reset the unit's busy 
status in Central Control. finish() also sets the I/O Complete interrupt, which 
we don't want at the end of a load. finish() call 
CentralControl.loadComplete(), which was resetting the appropriate I/O Complete 
interrupt bit, but by this time the IAR had been set, so the interrupt would 
occur anyway. The solution was for loadComplete() to call signalInterrupt(), 
which will re-prioritize any pending interrupts and reset the IAR.

This was actually a problem for both disk and card load operations, but 
apparently the KERNEL that gets loaded from disk is smart enough to ignore the 
spurious interrupt, but the one-card ESPOL loader is not. It usually worked in 
SyllableDebugger if "Run Silently" was not checked, but not otherwise, probably 
due to differences in timing.
