This property can be used to control how the SideMenu is opened using swipe gesture

bezel - only swipes from the side of the screen open the side menu
entireScreen - Swipe from any area of the screen will open the SideMenu

This PR adds support for setting stack root with multiple children, which is to be expected as stack can be initialised with multiple children.
Closes #4441

Remove some implicit anys and refactor tests

* Remove tests that test that lodash cloneDeep works

The following PR introduces improved support for Context api and other api's which wrap the root view.

## Context api
Navigation.registerComponent('navigation.playground.ContextScreen', () => (props) => (
  <TitleContext.Provider value={'Title from Provider'}>
    <ContextScreen {...props} />
  </TitleContext.Provider>
), () => ContextScreen);

## Redux
Navigation.registerComponent('navigation.playground.ReduxScreen', () => (props) => (
  <Provider store={reduxStore}>
    <ReduxScreen {...props} />
  </Provider>
), () => ReduxScreen);

## Plain Component - not changed
Navigation.registerComponent('navigation.playground.MyScreen', () => MyScreen);

This PR also upgrades the TypeScript version to 3.2.0 and RN version used in the playground app to 0.57.7

* New Android build flavor - `reactNative57_7`
* Unit test coverage is disabled, for some reason it broke after upgrading to RN 0.57.7

Initialize and pass mainWindow to commandsHandler

Fix name collision so autocomplete works

* Fix typo in setStackRoot animation docs

* Use 'enabled' instead of 'enable'

Until now controlling drawers touch gestures was impossible, drawers received gesture opening touch from the entire screen and that causes collisions with other gestures (which are implemented on the javascript side).

This commit adding modes for how sideMenu drawers gestures will receive opening touch.
```
{
  sideMenu: {
    openGestureMode: 'entireScreen' | 'bezel'
  }
}
```

- `entireScreen`: drawer gesture will trigger drawer opening from the entire screen
- `bezel`: drawer gesture will trigger drawer opening only from the center screen bezel frame

The default didn't change.

Refactor component name to be number also

Adding `android.enableAapt2=false` broke the build from Android Studio with an error `Execution failed for task ':app:transformDexArchiveWithExternalLibsDexMergerForDebug'`
Both command line and Android Studio builds worked fine after removing it.

Add title alignment to options

* Avoid calling component generators on registerComponent

* fix unit tests

* remove console.log

* fix coverage

* fix coverage

I believe there is a type in the docs. The title prop in bottomTab should be text.
