[Cheetahtemplate-discuss] PR to start on Python 3 compatibility

[Marc A. <msa...@gm...>]

I fixed a few small things that don't work in Python 3. It still doesn't
work in Python 3, but it's a tad closer and this is a small and easy PR to
review. Also I didn't want to invest too much time since the project has
not been active in the last few years and it's possible that the work could
go to waste if there's no one interested in reviewing it.
