Ideology Policies grant Adjacencies Over Flat Yields

Makes the specialist policies for each Ideology in Modern instead quadruple their respective yield adjacency. This applies to both Buildings, Improvements and also modifiers that grant wildcard adjacencies, like Bugandas adjacency on Lakes. The aim of this mod was to make the specialist game in modern more interesting, as well as make Buildings and adjacency more important. It also has the side effect of making Modern Wonders a lot better, since they can really boost adjacencies.
