Further streamline connected pawn evaluation Make even more clear what are the terms that contribute to evaluate connected pawns, and completely separate them from the weights that are now fully looked up in a table. For future tuning makes sense to init the table with a formula instead of hard-code it. This allows to reduce problem space cardinality and makes tuning easier. And fix a MSVC warning while there: warning C4804: '>>' : unsafe use of type 'bool' in operation No functional change.
