Remove support for legacy React Native props and add support for the
'trackColor' object. Retains support for the web-only equivalents as I think
this API is preferable to the one in React Native, both in terms of flexibility
and performance (no inline objects).
Fix#1382
Removes the following deprecated exports: `ColorPropType`,
`EdgeInsetsPropType`, `PointPropType`, `TextPropTypes`, and `ViewPropTypes`.
Remove all use of `prop-types` in the implementations of components. Flow types
are used instead, so there will no longer be runtime warnings related to props.
NOTE: Removes support for `className` prop.
Fix#1383Close#1477Close#1474Close#1489
Client-side hydration of server-rendered HTML now requires that `hydrate` is explicitly set in the `appParams` passed to `AppRegistry.runApplication()`.
