Tuned some pawns and evaluation constants Tuned values in pawns.cpp and evaluate.cpp after a SPSA session: 419k games 60sec 600nodetime. We have adjusted the PassedRank[] output of the SPSA session to keep increasing values with rank, and PassedFile[] output to keep the West <–> East symmetry of the evaluation.
