Cleaner autoresizingMask fix (refactor #9.)
Remove unintentionally committed commented out lines.
Add missing didMoveToParentViewController: calls.
Lock to KIF to ~> 1.0.
SGBDemoTabBarController.m needs to be compiled for the tests to run.
Setup SGBDemoAppDelegate for testing harness needs.
Slight code style improvement.
Revert to "check and fail first" instead of "indented if's" for push/pop sanity checks.

(Per request of project maintainer.)
Fix all (previously broken) tests.

The tests were broken because they were waiting for the "Screen #" navigation bar title to be gone, but the navigation bar would then contain a back button (in some cases) with that title. Now there is a separate label in the demo view so you can check for the appearance/absence of the navigation bar title and view separately.
Ensure views get removed along with popped controllers.
Document KIF tests (and add instructions to run) in README.
Don't attempt to add the swipe gesture recognizer if it's nil (< iOS7).
