Remove _compat module and _u function in favor of native unicode literals and project gardeningdrop-33

- DRY with dependencies
- Enable coveralls.io and add a coverage tox environment
  - A few tiny changes to increase coverage, but we're not at 100%
- Enable testing sphinx docs for all versions
- Publish CHANGES.rst on RTD
- Modern tox.ini and .travis.yml
  - Travis was still testing 3.3 and not testing 3.6.
  - Remove 'level' qualifiers from XML parsing and ZCML test cases.
    They add about 2s to run the tests, but they're important; see #13.
    That extra time gets lost in the amount of time it takes to spin
    tox anyway.
