This is a complete replacement of lang-german.txt. As mentioned before
the list was in wrong format (7 Bit) and couldn't reflect the German
Umlaute (see e.g. #485, #440, #439) at all.
The best I found so far and could serve as a starting point was
a gist from @MarvinJWendt, see
https://gist.github.com/MarvinJWendt/2f4f4154b8ae218600eb091a5706b5f4
Instead of ~8MB it's even bigger (~29MB).
Cheers, Dirk
