Removes PII from seeds file, updates Gemfile, and cleans up documentatio...

It's funny how I always find myself back on this project.

Remembered in my sleep that our seeds file had **[PII](http://en.wikipedia.org/wiki/Personally_identifiable_information)** in it, so this PR removes it.
Cleaned up the generation of the data as well by adding in the **[faker](https://github.com/stympy/faker)** gem.

Specified Ruby 1.9.3 and cleaned up the Rdoc README file.

Look good to you, @awaxman11 // @chhhris // @dmanaster? :smile:
