This adds six to the requirements.txt file in order to make some HTTP-related imports work across Python 2's httplib and Python 3's http.client modules. Tests were updated, including one change to the location of HTTPConnection - moving it from being accessed where it was imported rather than its canonical location inside of six.moves.http_client.
