Adding Language

[Nitrama]

I added support for different languages.

But I need help to support as many languages as possible.

If somebody knows a language well or has improvements for an existing language please just let me know.

New languages will be released with the next addon version.

As an example, I have created these 2 files.

Thanks :-)
