Website language selection should not translate language names

Currently the website language selection tool is translated to the current language of the website.

For example: if I have the German version open and I want to see the website in English, I have to select Englisch in the language list. This is an easy example, but if the website is in Russian and I don't know how to read Russian, there's no way I can choose my language.

The best way to solve this is to leave all languages written in themselves: English would be English, German would be Deutsch and so on.
