Implemented danish translation

[Morgenkaff]

Hi Aurélien!

First of all; thank you for a fantastic app!

I thought I would try to give a little back, and have made a danish translation for it. This is my first contribution to a project I'm not a part of, so sorry in advance if it is unwanted, done in a wrong way or anything else. (And please be kind ;) )

Just say so, if I should change anything.

Thanks again, and best wishes! Morgenkaff - Emil Harder
