Since the JS test modules have been renamed to have consistent naming, we add a method to actually run the test methods to use our existing abstraction.
The top-level package.json explicitly includes the directories it needs (vendor/.npmignore cuts down the cruft). The publish-beta.sh script essentially uses `npm pack` to package up the NPM module and then push it into an orphaned `beta` branch.
The target dependencies are discovered implicitly, and removing the use of explicitly defined dependencies actually resolved a very odd bug with Xcode when building ReactExample.app for a device.
