Infinite swap lock

If you look 3 moves deep and there are only ever 2 combos, the first move you do can be anything since it doesn't affect the game in anyway (assuming the first move is the non combo).
This causes an loop of doing nothingness..

Fixed on commit b61358b ,

Now moves are ordered in such a way that highest scoring moves are done before lesser scoring ones to ensure that you do not go in a loop of lesser scoring moves.
