Summary:
When composing scroll views, `this.refs[SCROLLVIEW_REF]` may refer to another higher-order scroll component instead of a ScrollView. This can cause issues if you expect to need it to be a ScrollView backed by an RCTScrollView.
The solution is to call `getScrollResponder()` - as long as all higher-order scroll components implement this method, it will make its way down to the true ScrollView, which is what ListView wants here.

Summary:
Remote images now support the `tintColor` prop.
Also picked nicer demo colors for the UIExplorer example.

Summary:
Change `RCTImageDownloader` so it stores the `RCTDownloadTaskWrapper` for reuse. Modify `RCTDownloadTaskWrapper` to use associated objects to store the completion/progress blocks.
Summary:
This PR adds 4 native events to NetworkImage.
![demo](http://zippy.gfycat.com/MelodicLawfulCaecilian.gif)
Using these events I could wrap `Image` component into something like:
```javascript
class NetworkImage extends React.Component {
getInitialState() {
return {
downloading: false,
progress: 0
}
}
render() {
var loader = this.state.downloading ?
<View style={this.props.loaderStyles}>
<ActivityIndicatorIOS animating={true} size={'large'} />
<Text style={{color: '#bbb'}}>{this.state.progress}%</Text>
</View>
:
null;
return <Image source={this.props.source}
onLoadStart={() => this.setState({downloading: true}) }
onLoaded={() => this.setState({downloading: false}) }
onLoadProgress={(e)=> this.setState({progress: Math.round(100 * e.nativeEvent.written / e.nativeEvent.total)});
onLoadError={(e)=> {
alert('the image cannot be downloaded because: ', JSON.stringify(e));
this.setState({downloading: false});
}}>
{loader}
</Image>
}
}
```
Useful on slow connections and server errors.
There are dozen lines of Objective C, which I don't have experience with. There are neither specific tests nor documentation yet. And I do realize that you're already working right now on better `<Image/>` (pipeline, new asset management, etc.). So this is basically a proof concept of events for images, and if this idea is not completely wrong I could improve it or help somehow.

Get the system font instead of Helvetica programmatically and add a virtual fontName called "System" that defaults to whatever the current system font is.

Summary:
Image source uri's prefixed with ~ are expanded into a full path to
the app directory.
For example: `~/Documents/foo.png` is expanded into `Users/arbesfeld/Library/Developer/CoreSimulator/Devices/977988DF-A8BC-4CE5-A27A-75807A6DF085/data/Containers/Data/Application/CBEFC261-5900-4EF9-8646-603BC57B094A/Documents/foo.png`.
This lets us store and use images from the application home directory with the `Image` component:
```
<Image source={{uri: '~/Documents/foo.png', width: 300, height: 300}} />
```

Fixes#1809
Even if a bridge has more than one root view, it's not supported by the js side
right now, and it will keep warning that those timespans had already been
recorded.
Summary:
Introducing the data structure NavigationRouteStack that focused on managing
navigation routes stack.
The goal is to make <Navigatior /> thinner by moving stack management logic into
its own class and make sure it's well-tested.
Teh next step will be cleaning up <Navigatior /> and add `NavigationRouteStack` to
`NavigationContext`.
Summary:
A minor improvement suggestion: `Navigator.getCurrentRoutes()` probably shouldn't return its `routeStack` backing array as-is, because the caller may mutate it, causing the internal state of the navigator to go out of sync. Instead a shallow copy of the routes should be returned.
I stumbled on this problem in my app by attempting to read the navigator state as follows:
```
let routes = Navigator.getCurrentRoutes();
let current = routes.pop();
let previous = routes.pop();
```
Which led to an exception at next navigation event.

Summary:
As discussed with @nicklockwood in the issue https://github.com/facebook/react-native/issues/1780, the error should be changed to a warning to not break fetch() to send a POST to a remote API without wanting to parse the reply. E.g. google sends back an empty 1x1px gif when POSTing something to google analytics.

Summary:
The `ScrollView` component tells the native side the subview indices of the views to make sticky. The problem is that, once layout-only views are collapsed, the indices are no longer reflective of the original views to make stick to the top.
Summary:
This enables code like:
```js
<ListView renderScrollView={() => <CustomScrollView />} />
```
where CustomScrollView might be inverted or support pull-to-refresh, etc.
