Title: Update to Rails 3.2.6 and omniauth-oauth2 1.1.0

I just updated the gemfile to Rails 3.2.6 and using the stable release of Devise and omniauth-oauth2. omniauth-oauth2 1.1.0 requires a state attribute to be passed from the provider to the client so that is the second commit.

You can see the companion update in the client app.
