Previously self.userInteractionEnabled defaulted to YES, and this
caused plenty of bugs for me when text nodes would silently steal
touches. It should default to NO, and callers who want tappability on
their text nodes should manually set .userInteractionEnabled to YES.
Summary:
Import the headers for control, image, and text nodes, as well as the normal display node and helper functions. Subclass headers omitted as they are intended to be imported in subclass implementation files, not public headers.
Test Plan:
`#import <AsyncDisplayKit/AsyncDisplayKit.h>` followed some time later by:
```
ASDisplayNode *node;
ASImageNode *node2;
ASTextNode *node3;
ASControlNode *node4;
```
Summary:
* Fixes#3
* Ordering: atomicity, then [optional] readonly, then value semantics (retain/copy/assign)
* Removed redundant `readwrite`
* No spaces between "getter = name" ("getter=name" instead)
* Property method overrides renamed as well
* self.isBlah, while technically not entirely correct, still resolves to [self blah], so left alone (@kimon had advice on this sort of naming issue last summer), and largely inconsequential
Test Plan:
* Compile and run
Summary:
* Moves ASThread.h from Private to Public visibility
* Moves ASThread.h from Private/ to Details/
* Changes public #imports from "" to <>
Test Plan:
```
#import <AsyncDisplayKit/ASDisplayNode+Subclasses.h>
#import <AsyncDisplayKit/ASControlNode+Subclasses.h>
```
