Allow editing EU4 areas/regions/etc.

Do you plan to update this wonderful tool of yours for Cossacks?

Namely they introduced areas and changed regions map modes.

It would also be extremely convenient if i could edit these files from within editor.

Current solution as of 0.9.7 is to use the areas/regions/super-regions/continents mode to view. To edit, use multi-selection to create the desired list of provinces, then copy the province IDs and paste them into the file.

It's not a direct solution but I think it will work for almost every use case.
