[Exports] Expose more modules for authors of custom components

Added some more exports to React that are either necessary or often useful for component authors.

I also exported React itself so that you can write just one destructuring assignment expression:
```
var {
  React,
  StyleSheet,
  View,
} = require('react-native');
```
