Devin Abbott f4a8efa452 Add react-native-web-player to core components docs
Summary:
This PR adds the interactive [React Native Web Player](http://dabbott.github.io/react-native-web-player/) to the docs. The web player is an embeddable iframe which runs React Native code using components from [react-native-web](https://github.com/necolas/react-native-web). For now, it's primarily for educational purposes, since only the basic components are implemented.

Some details:
- The iframe is loaded from MaxCDN using rawgit, locked down to a git tag.
- Asset paths (i.e. images) are resolved relative to `//facebook.github.io/react-native/`
- When viewed on mobile, it falls back to the syntax-highlighted code blocks.

The WebPlayer can be inserted into markdown by using the fences:

```
```ReactNativeWebPlayer

import ...

AppRegistry.registerComponent ...

`` `
```
