German translation: wording incorrect #166
Description
In the German translation of "change _ by " we find: ändere _ auf" instead of "ändere _ um_".
I couldn't find that typo in the language file. In line 576 in lang-de.js it says: "change _ by _": "ändere _ um _",
So actually, I don't know where it comes from. I guess @backface will know and can fix.. Thanks
