Add python3 support and remove need for temp file

[Drewsif]

There were also some code quality changes as well. I made it more pep8 compliant. I tested encoding and decoding between python 2 and 3 and it was working for me!

Hi Drew,

Thanks! I've made some updates in that regard too, plus added some new tools. I'll review your mods and make sure you get full credit for any pulls. It'll probably be another week before I can get to it.

Cheers,
