German translation

HI @all

I love the pimusicbox runs the whole day @home :smile:
I am from Austria and my neighbour dont speak english at all.
So if have translated him the index.html

In the pimusicbox the language is hardcoded so i changed it direct in the index.html

if someone need it here it is :smiley_cat:

The index is located here:

Only the frontend is translated not the Settings or any other site.
