This branch is only compatible with Python 2 (not Python 3) at the moment.

I'm not sure what's the status of Python 3 support in Klipper, but I'll try fixing the incompatibilities in my changes anyway.

Edit: I've fixed the errors I could find, you can try it on the dgus-reloaded-220828 pre-release.

I can't test the changes on a live install, so please let me know if you encounter any other issue.
