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.
