curses: restoring via menu

Clone the tty SELECTSAVED code in curses.  If you would be getting
the "who are you?" prompt (perhaps via 'nethack -u player') and
you have at least one save file, you'll get a menu of save files
(plus entries for 'new game' and 'quit') to choose from.  Requires
'#define SELECTDSAVED' at build time (only ntconf.h does that by
default) and when present, can be disabled by setting 'selectsaved'
to False in NETHACKOPTIONS or .nethackrc.
