Move PSQ score to Position This patch simplifies Position::do_move() by moving the PSQ score from StateInfo to Position and updating it inside the put/remove/move_piece functions. The downside is that there is now slightly more computation done in Position::undo_move(), but the fishtest results are Elo neutral.
