'toptenwin' defaults to false, so the high scores list at end of game
gets written to stdout by default. stdout might be a bit bucket if
the game is started from a menu somewhere or from Explorer or Finder
or something comparable. Even when started from a terminal, writing
to stdout is bad if running asynchronously ('nethack &').
Have Qt init force the 'toptenwin' option to true to show the high
scores in a pop-up text window. The "since you were in wizard mode
your score is ignored" line also goes to a pop-up text window now too.
An extra <return> is needed to dismiss that when quitting if you go
through the full disclosure sequence.
'nethack -s' writes scores to stdout before interface initialization
takes place, so isn't affected by this change. That's intentional so
that 'nethack -s > ~/myscores' can be used to capture the output.
