Python 3 Support

[t8y8]

After a quick glance at the code, I don't see any reason why this couldn't work with Py3.

In fact, I see more code written to prevent python3 than I think would be required to be compatible with python 3 :)

I'll take a more in depth review later and submit a PR
(I may just run futurize over it and compare the output)

Everything else is already compatible (I'm also not confidant the import stuff is necessary, that seems to be a quirk of the tool)

Will there be and official version that support python 3+?

[kittychou]

We don't currently have plans to update with an new version that supports Python 3+, but you are welcome to take the script and make the necessary modifications for your own use.

Can't promise a timeline, but if this is as simple as I think, I'll try and get to it within the next month.
