MVP version of data
Allow contributors to use Zeus for fast Rails commands & tests

[Zeus](https://github.com/burke/zeus) is a great gem that preloads
your Rails app so you can run commands and tests quickly. However,
it doesn't play well with the default "spec_helper.rb" that gets
generated when you install Rspec. The solution is to remove
"require 'rspec/autorun'" from "spec_helper.rb", which is what this
commit does.

This change does not affect those who do not have Zeus installed.
Running "rspec" from the command line will continue to work.
