Initial Vagrantfile, Dockerfile, and related configs.
Initial focus on vagrant docker provider, with custom vagrant backend.
Working docker container running postgres with custom configs.
Starting to get setup to run the rails app in a docker container.

* Also re-thought and updated how config works, making much heavier
use of environment variables and .env files so that the same code can
work in vagrant, docker, or direct on a dev machine.
Re-worked setup and configs a bit. The rails app runs locally again!
Much more progress, simplified configs and nearly working Docker build.
Lots of work on the Dockerfile and on a script to manage docker for dev.
Improvements to the dev env management script.
Tweakes to the env variables used to go with posgres updates.
Introduced a fig.yml file that will run a complete dev env on Docker!
Cleaned up Vagrant file, and minor tweak to Procfile.
Re-added Thorfile, tweak so Travis should pass, Updated Readme.
Fixed travis.yml to only trigger one build (with all env vars) instead of 4.
DB config env variable tweak. Should let travis pass.
Removing un-needed .env.test.
Adjusting DB config to remove separate postgis schema from search path.
