German language added

Verzweiflung, Wut und Schrecken
Begleiten ihren Sturz,
Und eine neue Welt
Entspringt auf Drupales Wort

This is almost all I can say in German, although I should say 'I can sing'. This is from the 'Die Schöpfung' by F. J. Haydn (The Creation). A wonderful piece of music I sung and played a few times which I would love to conduct at least once.

By the way, you can see I changed the ending just a bit. Forgive me for this. (Gerhard will tell you what it means...)

All this to say that I will not be able to see whether there is any bug with the new German language I added, including the og.module .po file. So please, if you spot one, let me know.
