PEP8 Support (ignore E5).
Renamed all CamelCase fields to lowercase/underscore equivalents.
Major API changes with lots of backwards incompatibility changes and destruction of existing data!

- Moved interaction with API out of management command into PageInsight.
- Model changes to all models to be more consistent.
- Added tox tests (passing on Python 2.7, Django 1.5-6)
- Images now stored on the file system - existing image data will be lost if migrated!!!
