Tuned some pawns and evaluation constants

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.
