Summary:
Simply add an `onLayout` callback to a native view component, and the callback
will be invoked with the current layout information when the view is mounted and
whenever the layout changes.
The only limitation is that scroll position and other stuff the layout system
isn't aware of is not taken into account. This is because onLayout events
wouldn't be triggered for these changes and if they are desired they should be
tracked separately (e.g. with `onScroll`) and combined.
Also fixes some bugs with LayoutAnimation callbacks.
@public
Test Plan:
- Run new LayoutEventsExample in UIExplorer and see it work correctly.
- New integration test passes internally (IntegrationTest project seems busted).
- New jest test case passes.

Summary:
NavigatorIOS supports four new properties:
- **rightButtonImageSource:** The source of an image to display in the top right. This must be a static image since UINavigationController only supports UIImages. Adding support for UIImageViews (or arbitrary views) is more complicated because custom views do not fade on touch and do not have hit slop the same way that UIImage buttons do. Usage: `rightButtonImageSource: ix('ImageName')`
- **backButtonImageSource:** Use a custom image for the back button. This does not replace the back caret (`<`) but instead replaces the text next to it.
- **leftButtonTitle**: Text for the left nav button, which supersedes the previous nav item's back button when specified. The main use case for this is your initial screen/UIVC which has nothing to go back to (since it is the first VC on the stack) but need to display a left button. This does hide the back button if there would have been one otherwise.
- **leftButtonImageSource:** Image source for the left button, super

Summary:
This provides a way to get notified when a bridge fails to load JS, allowing apps to handle the error.

Github Author: James Ide <ide@jameside.com>
Test Plan: run the UIExplorer app with the packager server not running, and verify that the notification is posted.
Summary:
When touches end or cancel, update self.state in
RCTTouchHandler to let iOS know that we are in an ended/canceled state.
This way we won't eat other touches because it still thinks we're in a
began/changed state.

Test Plan:
Scrolling in the back swipe area no longer busts gesture
recognition in Wilde.
Summary:
I made some changes to css-layout that changes how layout is
computed for absolutely positioned nodes inside absolutely positioned
parents that have borders/padding. There were also some other changes
made to css-layout that haven't been merged in yet.
@public
Test Plan:
Made a node as described above, saw that the layout is
computed differently than in the browser, updated Layout, saw that the
Layout is not computed correctly.
Summary:
Fixes#534:
```jsx
<SegmentedControlIOS
tintColor="#ff0000"
values={['One', 'Two', 'Three', 'Four']}
selectedtIndex={0}
momentary={false}
enabled={true}
onValueChange={ (value) => console.log(value) } />
```
This only supports string-based segments, not images. Also doesn't support full customization (no separator images etc); I figure this is a good MVP to lock-down a basic API
I also included a snapshot test case, but the images keep coming out funky. When I look at the sim, I see that the text labels show up for the selected segment, but the snapshot keeps coming out with no text on those segments. I tried forcing a delay, but same result. Is that explainable?
Obviously happy to change anything about the API, code-style nitpicks, etc

Summary:
@nicklockwood - Could I get a review of this?
Just took `RCTTextField` and ported it from `UITextField` to `UITextView` as you mentioned in another discussion, and removed any `UITextField` specific attributes.
- How do you think this should behave when there are subviews?
- Do you know how we can respond to the `UIControlEventEditingDidEndOnExit` event to respond to submit? Because `UITextView` isn't a `UIControl` we can't just use `addTarget` with `UIControlEventEditingDidEndOnExit`.
- Any other feedback?
Still going to look over the `UITextView` docs in more detail and make sure we expose all important options, and add it to the UIExplorer example, just putting this out here for feedback.
