Adding end to end tests for curate gem

These tests were originally added to CurateND, but are important to
verify that the curate gem is properly working. To get these tests
working, the spec/dummy app required several tweaks.

@TODO - Still need to resolve the generator so that we can re-generate
the underlying spec/dummy app and run the appropriate end to end specs.
