German Language

Add german language
Works not 100% ... e.g. the translation "<br>In the PDF printing dialog,#<br>Im PDF Druck Dialog," is in the file, but still displayed in English at the ITDB, but 99% are correctly taken from the file and in German ;)
Maybe there is a bug or something else neccessary to get 100% instead of 99% of the translation. But anyway it's better than no German Language at all I guess :D
