* [ASNodeController+Beta] Provide an option to allow nodes to own their controllers. We should certainly remove this before moving ASNodeController out of Beta. However, I think it will require at least ASCollectionNode to be able to retain its top level set of node controllers. Without this facility built in, it's very difficult for apps supporting both UIKit and ASDK to manually manage the controllers and keep them in sync with perfect timing. * [ASNodeController] Fix one of the #if's.
