React Native Compatibility

Summary:
**This PR depends on an unreleased version of `fbjs`, so DO NOT MERGE.**

When merged along with facebook/react-native#5084, facebook/fbjs#95, and whatever PR fixes facebook/react-native#4062 (which I will update this issue with when I push it), this fixes #26.

The changes to Relay itself are super minor here:

1. Remove the reliance on ReactDOM. The only use of ReactDOM is `unstable_batchedupdates`. So to fix, I abstracted the reference to `unstable_batchedupdates` to it's own module, and then took advantage of the "react-native" `package.json` option, supported by the React Native packager, to load the correct version of this function given the execution context.
2. Removed `react-dom` from peerDependencies (but kept it in devDependencies, for use in tests), and also upgrade the `fbjs` dependency to a (yet unreleased) version that provides better compatibility with React Native.
Closes #713
