Minesweeper: Implement some feature requests.

Someone was playing this game and suggested a number of improvements so here
we go trying to address them:

- Add "chording" support, where you can click a numbered square using both
  mouse buttons simultaneously to sweep all non-flagged adjacent squares.

- Mis-flagged squares are now revealed as such on game over, with a special
  "bad flag" icon.

- The game timer now shows tenths of seconds. It also doesn't start until
  you click the first square.

- Add the three difficulty modes from the classic Windows version.
