Title: Added german PO file with missing keys

Your .po file seems to be outdated, as some keys were missing.
I created a new one using http://www.icanlocalize.com/tools/php_scanner

Unfortunately I made the mistake to include the new keys in the de_DE.po file and not in your flat.po.
If you don't want to merge this pull request, you probably could update your translation file?
