Support Python3

[heynemann]

From my perspective it's pretty simple to do this. I'll try to land a pull request.

Any progress on this?

This project has some forks. At least in one of them, from znanja, he applies 2to3 module to convert the python2 code to python3. I also made a fork with the target of converting the code for python3. I only used the 2to3 to do that. Please refer to dev branch for the code converted. Didn't test yet.

I'd be happy to merge a PR that supports Python3.

I only applied 2to3 module to the scripts. Do you want to open a dev branch or I can make the PR on master?

[bbangert]

A PR off master sounds good to me.
