State Tracking and Limited Python 3 Support

This release adds in the ability to provide the state parameter for the OAuth2
authentication flow.

Additionally, minor changes have been made to upload in order to better support
Python 3.  This does not mark guaranteed coverage for Python 3 support, but
additional issues are invited for full support.
