[BREAKING] Call Navigation.events().bindComponent(this) to listen to lifecycle events

This commit introduces breaking changes to the way components listen to RNN events.


Background

Up until now, components could handle navigation events by implemented a set of callbacks:
* componentDidAppear
* componentDidDisappear
* onNavigationButtonPressed
* onSearchBarUpdated
* onSearchBarCancelPressed

While this worked fine for the most part, this was completely broken for HOCs as RNN invoked these methods only on the registered component (top most HOC), leaving it to the user to propagate these events down the HOC chain. See the discussion in #1642 for more details.


Solution

In order to support HOC use case, we're introducing a new api which will let any Component bind itself to receive navigation events:

```js
class LifecycleScreen extends Component {
  constructor(props) {
    super(props);
    this.subscription = Navigation.events().bindComponent(this);
  }

  componentWillUnmount() {
    // The subscription is removed automatically when components unmount, but they can be explicitly removed as well by calling `this.subscription.remove(); `
  }
}
```

It's still the users responsibility to propagate the `componentId` down the HOC chain, but by binding a component to RNN, it will be able to handle events as expected. Multiple components can be bound for the same `componentId`.


Consolidate event names

* onNavigationButtonPressed -> navigationButtonPressed
* onSearchBarUpdated -> searchBarUpdated
* onSearchBarCancelPressed -> searchBarCancelPressed

* V2: Peek and pop

* Add event when preview is dismissed in non commit mode

* tslint

* Refactor playground. Document preview api

* Added width prop

* Implement hybrid push/preview button

* Fixing small linting errors

* Work in progress

* Arbitary changes

* Improvements on API

* Cleanup RNNSplitViewController, allow mergeOptions

* Added documentation and better playground example

* Adding tests for coverage

* Find out why this test is failing.

* Only show split view on iOS

* Add test back in

* setRoot({root:{}})

* support setRoot with root, modals, overlays

* Update setRoot calls in playground app to new api

* Update setRoot on Android to new api

currently only supporting root node

* Update setRoot on iOS to new api

* fix unit tests
