port code to requests library, fix an import error for python3, bump version

[jeremyherbert]

Hi,

Please see this pull request which I have tested on both python2.7.6 and python 3.5.2. The main change is to use requests rather than the stdlib HTTPS stuff (the stdlib changed in this area between py2/3 so this was the easiest way to maintain compatibility with both). I also had to change some import statements to get it to work in python 3.

Version also bumped to 0.6, and the old python folder was deleted.

Sure, it could be nice to merge!
