Tweak initiative and Pawn PSQT (#1957) Small changes in initiative(). For Pawn PSQT, endgame values for d6-e6 and d7-e7 are now symmetric. The MG value of d2 is now smaller than e2 (d2=13, e2=21 now compared to d2=19, e2=16 before). The MG values of h5-h6-h7 also increased so this might encourage stockfish for more h-pawn pushes.
