Case contract

Input [terr_b, terr_w, prisoners_b, prisoners_w, passes, komi_tenths]; passes lists passing colours in order. Each pass gives one prisoner to the opponent; if the final pass was black, white hands one extra stone to black. Return [black_tenths, white_tenths, winner] with winner B, W or tie.
