Subject: [PATCH] Quit GMenu2X when window is closed in main screen

This helps when testing on PC.

I didn't bother to implement the same functionality for all dialog
event loops, since that would be a lot of extra work and not necessary
for the scenario that I need it for: clean exit when running under
Valgrind.
