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.
