Implement S-Chess The value drops=2 in the gameState controls whether gating in pieces from the holdings is possible, and implies holdings even if holdings=0. New incarations of Cardinal and Marshall are added to the piece types, under the names H and E. Gating has to be entered as promotion ('/' in stead of '=' is allowed). King does no longer have to be the last piece type; a macro PIECES has been added to indicate the number of piece types.
