The language system is actually being changed in Bugdar 2.0, but the roadmap is also changing right now for Bugdar 1.3, which could also affect languages... so I haven't finished implementing this, yet.
As I noted on the blog, Bugdar 2.0 changed directions during the early stages of development. I have new plans for the translation console, but it does not yet exist. I do not have any translation files (I'm also not personally aware of anyone who has translated Bugdar into German). If you do, you can post the files in the forum and I will make the thread sticky.
