* Update events.md

* change query param to text

This commit also upgrades TypeScript to version 2.9.x

`wether` -> `whether`

title was renamed to text

`relase` ->` release`

This resolves an issue where currentTabIndex, for example, was not cleared properly
if it was set in initialOptions as it was cloned each time clearOptions was invoked.

This reverts commit 9d4eea835a.

[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

[BREAKING] Buttons refactor

* Support setting single button
```js
  topBar: {
    rightButtons: {
    }
  }
```
* [BREAKING] Rename button.title to button.text

* Set TopBar default background color (white)

Command animations did not take default options into account when resolving animation options.
This commit fixes that, TopBar options still need to be addressed.

This reverts commit 6c451d3744.

This reverts commit fc493775eb.

This commit introduces an option to control the way components are pushed into the stack.
When pushing components into a stack, they are pushed the moment they are measured.
If `waitForRender` is true, components will be pushed only after the initial render.

api:

```js
options: {
  animations: {
    push: {
      waitForRender: true
    },
    showModal: {
      waitForRender: true
    }
  }
}
```

`largeTitle: true` is not valid and throws error
