Adam Comella ee8496f364 iOS: Support HTTP headers for source prop on <Image> components
Summary:
Allows developers to specify headers to include in the HTTP request
when fetching a remote image. For example, one might leverage this
when fetching an image from an endpoint that requires authentication:

```
<Image
  style={styles.logo}
  source={{
    uri: 'http://facebook.github.io/react/img/logo_og.png',
    headers: {
      Authorization: 'someAuthToken'
    }
  }}
/>
```

Note that the header values must be strings.

Works on iOS and Android.

**Test plan (required)**

- Ran a small example like the one above on iOS and Android and ensured the headers were sent to the server.
- Ran a small example to ensure that \<Image\> components without headers still work.
- Currently using this code in our app.
