Summary
-------
While executing an interrupt driven commands it may be executed from the map on
one thread and executed from the queue at a different thread
This will cause the following exception to be thrown:
java.lang.IllegalStateException: CoordChangeXCommand already used.
- Avoiding throwing exception in case of interrupts and synchronizing the
changes in [used]
- Avoiding executing interrupt in case of commands that doesn't need locks
- Changing the debug message for execute interrupt to explicitly mentioning it
is an interrupt command
This addresses bug OOZIE-684.
