Above file is a standard
unified diff used everywhere in the code development world. This mainly contains the changes to the original file. I can't and won't provide a edited version of the original Add-On, this would be inadequate and might conflict with some licencing terms.
You can apply this patch with
patch < filename_of_the_patch.diff or you edit the xml file by your own. Basically lines starting with a
+ have to be added to the xml files, lines starting with
- have to be removed. Look up the exaxt syntax in the article I linked above.
