Converts dev env to use Docker

[conorsch]

Ready for review.

Closes #83.

Leverages the new Molecule-based testing and development workflow to spin up Docker containers for local development, rather than full VMs. Should make for a much more pleasant experience locally.

To test:

1. Confirm CI is passing (both Travis and Circle).
2. Run make dev-go and wait for the service to come up.
3. Browse to the localhost port displayed on screen and navigate through the site.
4. Confirm you can use the site locally and no errors are reported.

123 has been merged, so this is ready for review now.

Thanks for careful review, @redshiftzero. Locally I had gitignored static assets sticking around, and their continued presence between builds was causing the site to render when it shouldn't. Added a make clean to strip out those local assets ad-hoc.

Ported the dev env database settings to use a Postgres container, rather than a local sqlite database. Since Travis was still using sqlite, I disabled Travis, since Circle runs all the app tests in a more prod-like environment (via containers).

The test superuser no longer works for me

Fixed, but you'll need to run make dev-createdevdata in order for that account to be provisioned. Then it should work.

Take it for another spin and let me know.

So, the static assets are still not loading for me. Specifically I'm getting a 404 on the homepage for main.css and build.js (both referenced in the template in securethenews/templates/base.html).

When I hop in the STN node docker container and try to run the build task manually gulp is not found:

$ docker exec -it b034f6754da6 /bin/ash -c "cd /django; npm install; gulp build:production"

Am I missing something?
