It embeds RealmJS and GCDWebServers frameworks. This fixes#58, where there were issues with building for devices rather than just the simulator.
Some changes were made so that RealmReact.m didn't need to be weakly linked to libReact.a since that would actually cause any executable that uses this framework from being able to compile with bitcode.
The idea is that we will have an NPM module that should always be required to use the Realm JS API. It will handle the underlying implementation details depending on which environment it is being run in (i.e. JavaScriptCore, Chrome, Node).
The focus here was on stubbing out the machinery required to get React Native Chrome debugging working with the Realm API by leveraging synchronous requests. The app itself will need to run a web server that responds to these requests.
