Added RCTImageSource

Browse Source 
Summary:
public

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.
