Various clean-ups in preparation for 3.0: 1) Add a built-in default game which is used for the case when Sudoku is started as a plugin and no sudoku.ss exists - this prevents a time-consuming game generation; 2) Allow the user to abort a game generation by pressing any button; 3) Save the current state when user exits via the Quit button (previously, Sudoku only saved when quitting from the main menu); 4) Add a new "edit menu" for when the user is manually entering a new game, rather than displaying all options.
