Summary: To prevent layout popping, when inserting images inside text we would render a blank placeholder image while the real image was loading. It turns out that this isn't necessary, as we can just specify the size of the image without having an actual image to display.

Summary:

Previously, `<Image>` elements embedded inside `<Text>` ignored all style attributes and props apart from `source`. Now, the `width`, `height` and `resizeMode` styles are observed. I've also added a transparent placeholder to be displayed while the image is loading, to prevent the layout from changing after the image has loaded.

Standardises the image decoding logic for all image sources, meaning we get the benefits of efficient downscaling of images from all sources, not just ALAssets.

Summary:

The +[RCTConvert UIImage:] function, while convenient, is inherently limited by being synchronous, which means that it cannot be used to load remote images, and may not be efficient for local images either. It's also unable to access the bridge, which means that it cannot take advantage of the modular image-loading pipeline.
This diff introduces a new RCTImageSource class which can be used to pass image source objects over the bridge and defer loading until later.
I've also added automatic application of the `resolveAssetSource()` function based on prop type, and fixed up the image logic in NavigatorIOS and TabBarIOS.

Summary: public
The image loader was previously returning on the main thread, which could lead to poor performance due to various call sites doing further image processing (resizing, cropping, etc.) directly in the completion block.
This diff modifies the loader to return on a background thread (the same one used to load the image), and updates the call sites to dispatch to the explicit thread they need.

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.

Summary: @public
This diff implements inline image support for <Text> nodes. Images are specified using <Image> tags, however all properties of the image are currently ignored apart from the source (including width/height styles).
Images are loaded asyncronously, and will trigger a text re-layout when they have loaded.
