Simplify Weak Lever This is a simplification that integrated WeakLever into doubled pawns. Since we already check for !support for Doubled pawns, it is trivial to check for weak lever by just checking more_than_one(lever). We also introduce the Score * bool operation overload to remove some casts in the code.
