Support EU4 1.14 map regions structure

[mmyers]

1. They added a area file which is like the old region file containing province numbers:

   western_mediterrenean_area = {
      1293 1294 1295 1296 1297 1298 1300 1301 1302 1303 1304 1305 1307
   }

2. They changed the region file to a new format - it now contains area names (from the area file) rather than province numbers:

   france_region = {
      brittany_area
      normandy_area
      provence_area
      guyenne_area
      languedoc_area
      massif_central_area
      savoy_dauphine_area
      lorraine_area
      picardy_area
      seine_area
      loire_area
      bourgogne_area
      pyrenees_area
   }

3. They added a new superregion file - consisting of region names from the new region file:

   india_superregion = {
      bengal_region
      hindusthan_region
      rajputana_region
      deccan_region
      coromandel_region
      west_india_region
   }

4. They added a new provincegroup file which works like the old regions did containing province numbers:

   mytestgroup = {
      1 2 3
   }
