Solitaire: Allow automatic moves to end the game and animate

Previously, if a tab-move moved all the remaining cards to the
foundations, the game would not notice until you moved a card
away and then back again.

I had to add a 1-frame delay to starting the animation, so that it
would have time to re-paint the foundation in that case.
