Long Diagonal Tweaks a) Reduce PSQT values along the long diagonals on non-central squares and increase the LongDiagonal bonus accordingly. The effect is to penalise bishops on the long diagonal which can not "see" the 2 central squares. The "good" bishops still have more or less the same bonus as current master. b) For a bishop on a central square, because of the "| s" term in the code, the LongDiagonalBonus was always given. So while being there, remove the "| s" and compensate the central Bishop PSQT accordingly.
