Fix grandfather solver

The rules say you can redeal if there are no other moves possible, but the game actually allows redeals at any time. Also allowing it in the solver, makes a huge difference in the number of games possible to win. Especially moving a king pile from one empty pile to another blocked redeals - which players gentle ignore (and as such the written rules make little sense).
