Footer/Internationalization: Show languages dropdown as written in their original way

[mariobehling]

In the footer we have a language dropdown that shows all languages in English. Expected is that languages show up as they are written in their own language, e.g. German should be Deutsch, Vietnamese should be Tiếng Việt etc.

Unfortunately spelling is wrong in several languages. Also capital/non caps is not following any standard and languages are not sorted in any logical way. You could compare how this work e.g. on eventbrite, Wikipedia etc. For the sorting I also recommend we follow Wikipedia.
