Shuffling players mid game

[stevenocchipinti]

The shuffle button is always visible and right next to the undo button. If this is accidentally pressed, you can't undo that!

To guard against this, it should either:

• Not be allowed mid-game (maybe too forceful considering that come-and-go nature of the game)
• Prompt the user reconfirm it is intended if players have any points / scoring history
• Be less easy to press
• etc
