I don't use this plugin myself, but here is a
link for a version I sent to @salfter in a pm. It is partly based on his port, but modified to work on both python2 and python3.
I didn't test this one, so it should be treated as a base to build on, rather than a functional complete port.
Edit: Trying out this version, it is obvious it needs a lot of work. This is better done by someone who is familiar with this plugin.
