Gemfile
- removed version rails to stay up to date with current stable
  rails version until it causes problems.
- moved from cancan to cancancan because cancan is dead.
  LONG LIVE CANCANCAN!
projects_controller_test
 fixed broken test.  At some point we changed the permitted
 parameters in the controller to not allow name and
 description unless the user was a RepositoryUser.  This
 caused the tests to fail when ProjectUser and CoreUser
 attempt to create a project.  It used to redirect_to
 root_path because of the CanCan::AccessDenied, but
 when we changed the permitted parameters, it started
 to throw ActionController::ParameterMissing before
 getting to CanCan::AccessDenied, so it needs to expect
 a 403

As a side note, I have tested RADS against ruby 2.1.2,
passenger 4.0.41, and rails 4.1.1 and ...
ALL TESTS PASS
