Implement castling

MoveGen() now also generates castlings. Legality is tested by the kludge
of replacing the Rook by a second King during the (early) move generation
in the next ply. MakeMove() is refactored to make sure both King and Rook
victim are saved. In addition promotion is now implemented by OR'ing the
promoInc into the piece code,tomake the engine resistent to promoting an
already-promoted piece (e.g. due to hash-move mixup).
