v3.3.3-beta1 - MacOS keyboard style & conflicts

CTRL-Q does nothing for VASSAL on Windows (unless mean Linux?). But Alt+F4 would quit VASSAL on Windows, and this is an accepted keyboard combo for Mac module designers.

I think it would definitely be worthwhile to put some thought into this moving to VASSAL 4, to exclude certain keyboard combinations that are problematic for Windows / Linux / macOS.
