Not actually existing Nationalities selectable as player

Particularly empty, none and slave make no sense, but the revivalist ones don't really fit either. I guess the best way would be to split the arrays in App.Data?

And it's missing Zimbabwean too. Probably want to check for Rhodesian as well (white Zimbabweans get a special nationality, and it's mostly done in code, not data).

Hmm, well I finally found the correct data, which is good. Knew it had to be in there somewhere.

Not sure if I need to do anything special for Rhodesia since it sounds like it should be set to Zimbabwe and just display as Rhodesia.
