Minesweeper: Show popup on win/lose

[HeyITGuyFixIt]

When playing Minesweeper and you win, there is no indication that you won, it only shows that you have 0 flags left, but there is a message printed to the console saying "won". When you lose, the mines are slowly revealed and a message is printed to the console saying "lost".

Could you add a popup or some other visual indicator that states you won or lost?
