Porting to Python 3

[jacopofar]

Hello,
I've ported the script to Python 3, it's here, you may want to link it or get it back as a git branch.

Unfortunately, the code does not work on Python 2

you should fork this repository, then fix some incompatible code. Then make a pull request. I think it is a better way to contribute and credit the author of this postagger

The problem is that my changes break the compatibility with Python 2. I forked the repo, but a PR+merge would break it for Python 2 users.
