German translation done

Hi @KajMagnus

you seem to be the master of desaster when it comes to translations ;-)

I think Talkyard is the best solution for adding comments to websites done with Ghost, thank you for sharing this great project. Unfortunately I need it in German frontend language, so I've done and contributed a full German Translation (informal "Du" version).

Please find my Pull Request #71 in your GitHub repo.

As far as I see I can't add it to my installation without some work from your side, so please kindly inform me when I can update my installation to use it. :-)

Let me know if you have any questions or need more ...
