Summary:
This re-implements sticky headers in JS to make it work on Android.
The only change that was needed was to expose a way to attach a an animated value to an event manually since we can't use the Animated wrapper and `Animated.event` to do it for us because this is implemented directly in the `ScrollView` component. Simply exposed `attachNativeEvent` that takes a ref, event name and event object mapping. This is what is used by `Animated.event`.
TODO:
- Need to check why momentum scrolling isn't triggering scroll events properly on Android.
- Remove native iOS implementation
- cleanup / fix flow
**Test plan**
Test the example list in UIExplorer, test the ListViewPaging example.

Summary:
This adds support for `Animated.event` driven natively. This is WIP and would like feedback on how this is implemented.
At the moment, it works by providing a mapping between a view tag, an event name, an event path and an animated value when a view has a prop with a `AnimatedEvent` object. Then we can hook into `EventDispatcher`, check for events that target our view + event name and update the animated value using the event path.
For now it works with the onScroll event but it should be generic enough to work with anything.

Summary: @public
This diff does a couple of things:
- Move all the code in a src/ folder
- Move bezier.js in the Animated folder
- Rename Animated.js into AnimatedImplementation.js and adds two entry points: AnimatedReactNative.js and AnimatedWeb.js
- Implement very dumb polyfills for flattenStyle, Set and InteractionManager
- Import my work in progress demo.html file to make sure that the code is actually working.
Everything is not working correctly:
- It calls forceUpdate on every frame and doesn't use bindings because setNativeProps is not implemented
- None of the style: {transform} are working because React web doesn't know about the array notation for transform
- The demo need more work
