appleguy 223f1c9a36 [ASDisplayNode] Consolidate main thread initialization and allow apps to invoke it manually instead of +load. (#798)
* - [ASDisplayNode] Consolidate main thread initialization and allow apps to invoke it manually instead of +load.

Additionally this has a few minor fixes for Yoga support, and adds some basic
but universally valuable callbacks like -nodeDidLoad to ASNodeController.

* Small fix for handling _layoutVersion.

* Remove poking the scale accessor
