I improved the implementation of Seirawan Chess in Fairy-Max. It now has
the gating moves fully integrated in its search process, so it should be no
longer possible to surprise it by gating. (With the exception of gating at
the Rook position in castling.) In theory it can still be stupid, because
it does not realize there is a last opportunity for gating. But since I
built in a large preference for gating moves, it always gates early, so it
is not likely to be ever left with un-gatable pieces in hand.
