Make Silk Great Again and Upgrade Dev Project

[hanleyhansen]

What

This PR is an attempt at upgrading the included project with silk to make local development work and easier for contributors. It also fixes an issue with the usage of the django render function

• Add default migrations for example_app
• Use new templates structure for new Django
• Get template discovery to work
• Add development instructions to readme
• Fix usages of render in silk and project
• Fix six import. Oversight from this commit: 48b7416
• .util seems to have disappeared from the face of the earth so need to rework anything that was using it
  • bring back delete_all_models()
  • bring back mock_data_collector()

Why

If we make it easier for devs to contribute to this project it'll be easier to help it move along.
