Never castle when King has other initial moves

Never castle when King has other initial moves

The ApplyMove routine assumed that any lateral King step of more than
a single square was a castling, and then swung the nearest piece in
that direction around the King. This failed in Grande Acedrex, where
the King can (amongst others) jump 2 squares sideways as an initial move.
So we now first check if the King has its moves redefined in a way that
does specify no castling but does specify other initial moves, and perform
any move as just a simple King move in that case.
