Marco Costalba 4f5680950a Add min pawn-king distance to endgame evaluation ...

At endgame time push the king near his pawns (actually
one of them).

Original idea is from Critter (although slightly different),
implementation is mine and is completely different from the
original, in particular it is different the algorithm to
compute the minimum distance from pawns.
