Pieces should not go through each other (except knight) #3

Chess rules need to be updated to make sure pieces can't move through each other.

This necessitates white/black queenside/kingside castle flags. The question is, where will the flags reside? Should they be fields of various ChessPieces, or should they be part of the ChessBoard class?

My thought on this was that we would update the logic of ChessPiece.validateMove() (and for specific subclasses for each chess piece type) to check the path between the current location and the target location and throw IllegalMove or some other exception if somebody is in the way.

Closing this issue since we're now going to be relying on the chess engine (GNU Chess) to decide if moves are valid or not. The "view" on the android side will just be dumb and put the chess pieces wherever the engine tell it to. So once the GNU Chess integration is done, this won't be a problem anymore.
