Added property to the content view controllers to automatically navigate to the next view controller as long as we're not on the last one.
Use instanceType instead of id.
Removed unused moveToPage... method and replaced it with more generic moveNextPage method.
We need the onboarding view controller to be the delegate on the contents even if we don't want fading.
Added auto-navigation to the first onboarding demo.
