First stab at getting Travis hare-y.
Tweak readme.
Add default rake task (rspec).
Add coveralls.
Forgot to bundle...
Tweak rubocop settings. Increase line length.
Add comments. More linking.
Add TravisCI and Code Climate badges to readme.
Add code coverage badge too.
More linting.

It feels so good to let rubocop run rampant and tweak code based on its
suggestions. Seriously, ya'll should try it sometime. Very relaxing.
Add rabbitmq to travis.

This is supposed to already exist, I thought. Let's try installing it in
a before hook.
