Michael Schneider aecd36a4df [ASViewController] Support optional node (#3021)
* ASViewController can be used without a node
- If a node isn't provided by developers via -initWithNode:, a default one will be created and used internally.
- This allows developers to use ASViewController like a normal UIViewController and as a base class for all view controllers among which some use a node hierarchy and some don't.

* Update ASDKgram to use a shared base ASViewController

* Minor fixes in ASViewController:
- If its node isn't provided by users, don't replace the view controller's view with the default node's view because it might be loaded from a nib.
- Init a vanilla ASDisplayNode if a node isn't provided.

* Some smaller cleanup

* Remove dummy node for ASViewController if it’s used without a node
