Solitaire: Ability to automatically solve the end of the game

Browse source 
In Solitaire, when the stock stack is empty and all cards have been
revealed, finishing the game is trivial, since you only need to sort the
already visible cards onto the foundation stacks. To simplify this, the
game will now give you the option to finish the game automatically if
these conditions are met. It then sorts the cards with a delay of 100ms
between each card.
