Rails 4 includes strong parameters and removed attr_accessible
(protected attributes). I removed the strong_parameters development
dependency and added it to all non-4.0 appraisals. I also added the
'protected_attributes' gem to the 4.0 appraisal because the test suite
examples make heavy use of attr_accessible.
* Add Ruby 2.0 support to the Appraisals
* Update travis to test 2.0.0 with the 3.2 gemfile. Clean up the travis
matrix to favor the include syntax over exclude.
* Edit gemfile.locks to point to relative paths.
> Use a pessimistic version in the Gemfile for gems that follow semantic
> versioning, such as rspec, factory_girl, and capybara.

* Upgrade dependencies so specs run on new Bourne.
* Use semantic versions in step_definitions gems.
* Rely on ActiveSupport::Dependencies.clear for reloading constants.
