Python3port

That should be the final version working in python 2 as well as in python 3.4. I also corrected the README saying that now Python 3 is supported as well.

It's missing the topic of the license which I answered you in the previous email. I don't have problems with any permissive license as long as it is permissive and clearly defined (then it could be used everywhere).

Please don't forget to review the code and give feedback.
