1) Fix compiles using wx 3.x and 2.8.

2) Fix passing wxString to common/config_params so lookup keys 
   can be dynamically generated.  This gives ~/.kicad files all the colors.
3) Fix LEGACY_PLUGIN so it loads all layer types and masks properly.
4) Extend the table in router/pns_index.h to 128 from 64.
