Add deep linking support to IntentAndroid

Browse Source 
Summary:
Add a method to handle URLs registered to the app,

```js
IntentAndroid.getInitialURL(url => {
    if (url) {
        // do stuff
    }
});
```

Refer - http://developer.android.com/training/app-indexing/deep-linking.html#adding-filters

The API cannot be same as the iOS API (i.e. as a constant), as the activity is not availble at the time of module initialization. Moreover, multiple activties can share the same bridge instance, and the activity itself is not a constant. Hence the initialURL can change.
Closes https://github.com/facebook/react-native/pull/4320
