Update to work with KWin 5.27
The KWin scripting API reference is quite old at this point, and so seems to be this script. I tried to run it but there were a few problems. Firstly saxon8 doesn't seem to be available anymore, the new version (saxon-he 12) seems to work the same though. And second, some of the files referenced in the script don't exist in the generated doxygen xml files. If you have time, can you please update this script? Would be great for all the KWin scripters out there!
