Added RCTDataRequestHandler Summary: public Added RCTDataRequestHandler, which is responsible for loading data URLs. This moves the logic for data URL handling out of RCTImageDownloader (no longer needed) and into the RCTNetwork library, where it makes more sense. This also means that it is now possible to load data URLs via XHR, and use them for purposes other than just images.

[Image] Add onLoadStart, onLoadProgress, onLoadError events to Image component 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.
