Fixed turn-taking. (Hopefully) fixed 7 card in AI

Aaron - I fixed up those bugs we were seeing. I'm going to bed now, but
in my time testing I saw issues with the 13 card. Once it did nothing,
and once it annihilated one of my pawns (it showed a -6 in getState, so
it was gone for good). Theoretically 7 should be working in AI, but I
haven't had a chance to test it yet. Good luck!
