Spec updates

Made some small improvements to Gemfile for development. Changed some of the controller tests and the model/user spec to the new expects syntax. If you guys agree with this, I'll do that for the rest of the specs as well as add in some re factoring as I see needed. Would also like to stub more in the controller tests for some speed. 

Found a few duplicate calls to 'get :index, :post' that were un necessary.
