Title: Change Rails Dependency to greater than 3.0.7

I ran into this issue when installing Factory Girl Rails

Invalid gemspec in [/home/vagrant/.rbenv/versions/1.8.7-p352/lib/ruby/gems/1.8/specifications/factory_girl_rails-1.7.0.gemspec]: Illformed requirement ["# 3.0.7"]

Could not find factory_girl_rails-1.7.0 in any of the sources
Run `bundle install` to install missing gems.

I didn't have Rails 3.0.7 installed on my machine. This should fix that issue of not having Rails 3.0.7 during development.
