Fixed an embarassing Chess960 bug found by Alexander Schmidt. It turned out that we used do_move_bb to update the king and rook bitboards when making and unmaking castling moves, which obviously doesn't work in Chess960, where the source and destination squares for the king or rook could be identical. No functional change in normal chess.
