Initial rails setup

Here's our initial rails project with a few configuration modifications made that we'll need:
- Heroku requires the `rails_12factor` gem (I've set it to only install in the production environment)
- Modified `db/database.yml` to look for a localhost postgresql using username "action", no password
- Added a placeholder brochure index route, so we don't just get an error when loading the site.

I set this up and tested on heroku successfully with specifically rails 4.1.0 and ruby 2.1.1p76:
