Simplify minPawnDistance This is a functional simplification which fixes an awkward numerical cliff. With master king_safety, no pawns is scored higher than pawn(s) that is/are far from the king. This may motivate SF to throw away pawns to increase king safety. With this patch, there is a consistent value for minPawnDistance where losing a pawn never increases king safety.
