Extending the vanilla themes

[boformer]

I thought about it again: It makes sense to allow users to add their own buildings to euro/int theme (by adding them to the config).

It is the easiest way to use custom assets with this mod.

For example, users could add these buildings to the european theme: http://steamcommunity.com/sharedfiles/filedetails/?id=446190120 http://steamcommunity.com/sharedfiles/filedetails/?id=446201704

And all of these to the international theme: http://steamcommunity.com/sharedfiles/filedetails/?id=423659623

To make it futureproof, vanilla buildings should be never be saved in the config (isBuiltIn field for Configuration.Building)

Nice idea! This way 'International' and 'European' themes of config will only contain additional custom buildings. But themes should also have isBuiltIn flag (as it is now) because vanilla buildings must be saved to config it a theme itself is not built-in.
