updated German languag file (xml)

Since there were some "glitches" in the existing German language file I tried to fix them as best I could. Some entries just didn't make any sense and I had to look at the english version to figure out what the meaning of some of the entries were.

Feel free to use it for your filevista system.

Thank you for the fixed german language file, we will include it in later versions
