Improvements in Xray Reports

Hi,

is it possible to improve:

• the german "Rückverfolgbarkeitsbericht" (should be "tracebility report" in english)?
• A spelling error on top: Deffekte should be Defekte
• And the userDisplayName instead of the User ID.

Also, there are several wrong translations of "Defect":  It should be "Defekte", but sometimes they are refered as "Mängel"

Best Regards
Manuel
