The German translations have been updated.
I also adjusted some old translations if there were spelling mistakes or if I thought the new translations fit better in parts.

@hanzei Want to take a look?

Thanks a lot @vorlif ! I left a few comments, and would appreciate it if you could response.
It seems like @hanzei are busy, so I'll merge this if there is no comments from @hanzei until cutting new release.
