Remeber last-moved piece in only one Board square

The amount of game-state data (castling rights, e.p. state...) carried
along in the extra rank above the real board is getting a bit out of hand.
Rather than storing rank and file of the last-moved piece in two separate
off-board squares in that rank, we now combine them into a single number
(which would still allow boards of upto 64 files).
