Title: Center Interaction Mode can become out of date if the center view controller is manipulated while the drawer is open.

I've seen a corner case where if you push a view controller onto the center view controller while a drawer is open, the user interaction state will no longer be correct. This is due to how we are directly setting `userInteractionEnabled` to NO for the `topViewController` of the center view controller.

I have a more elegant fix coming soon.
