- updates circleci config to better support multiple python versions
- remove unused dateutil library
- remove unused nose library for testing
- fixes unicode() function for py3
- remove metadata claiming support for py26 and py34
- remove unfinished test (causes problems with py2's unittest
  discovery)
- fix reload() function for py3 support
