Add Multi-Language Support (almost finished)

approx. 90% are already translated. At the moment 2 languages are included. English and German. If you are interested, feel free to add more translations. See the maintenance.php for more information. The Frontend is almost done. Some translations in the notification system are still pending.

I am aware that the language files still have some optimization potential, but after 3 days of localization, I don't feel like doing that right now.
