python 3 compatible

[saemideluxe]

Hello
Thanks for this nice project. I wonder if we could make the package python3 compatible? I know that the fork at grandemk/pypub has a working python3 version. Since this repo is the source for the pip packages, I think it would be appreciated if we can update this repo or merge it with grandemk/pypub.

Oh I never noticed this, I made it for a personal project without thinking about it ^^'
I'm not sure that all of my modifications are ok as I was pursuing a specific goal without thinking about distribution to other people
[EDIT] And there seems to be better implementation in the pull request anyway ;)
