Specify ruby version

Ruby set to version 2.0.0-p598 to maintain parity with Heroku
Configure Travis CI

I intend testing to be important in this project and wanted to use it as
an opportunity to test out Travis CI
Update Travis CI Settings

Using Postgresql with Travis CI doesn't work right out of the box.
According to the [docs](http://docs.travis-ci.com/user/postgresql/) you
must first configure the database with the `postgres` user and then make
sure your database.yml file matches up. Since I don't want to re-work my
local test environment to accommodate this flow, I am using a separate
database.yml file for Travis.
Quote database name to avoid a psql syntax error
Update README file

Use more familiar markdown syntax and format based on previous projects.
Also add Travis CI image.
