augment Qt Info menu

Add ^X (as "Attributes (extended status)") to the "Info" drop down
menu, also Overview, and Annotate.

Attributes and Overview work, Annotate results in running southeast.
Existing entries Conduct, Adjust, and Skills execute nethack's '?'
command so I didn't bother holding back on adding Annotate.  Other
existing entries (Inventory, Discoveries, Spells, and Name) work.
If there's any sort of pattern involved, I'm not seeing it.

The Game menu has "Save", which shows up and works, but that's
supposed to be followed by "Quit" which doesn't show up when the
menu is used.  This doesn't attempt to deal with that.

Command+q keystroke, which should close the application, behaves
the same as previously mentioned "quit nethack" in nethack menu:
runs nethack's '?' command and then resumes play.
