Fix tests, add py35

- Add Python 3.5 support on travis

- pytest-cache has been merged into pytest [0] and is no longer
  separately maintained, so pytest-cache-related requirements are being
  updated.

- Flask-Mongoengine latest stable is broken on Python 2.6 (but fixed in
  master [1]), so its version is being restricted for now.
