Options.java was missing from previous commit

This commit removes NavigationOptionsListener as it was not needed anymore.
As a result, it uncovered a few issues which this commit also aims to fix.

* Set SideMenuController as parent of left, right and centre controllers
* Select tab by id with tabSelector interface
* mergeOptions now also applies options after merge - in ViewController base class
* Pull presentation logic from ComponentLayout to ComponentViewController

This commit also consolidates index files in the playground app

* Cover OverlayManager with unit tests
* Add e2e to test Overlay unmount

* Assign commandId to async commands

* CommandListener refactor

Pull listener out of Navigator and implement NativeCommandListener for native commands

* Emit onNavigationEvent when commands complete

* Rename timestamp to completionTime

* Rename NavigationEvent to EventEmitter

* Rename sendOnNavigationButtonPressed to emitOnNavigationButtonPressed

* Emit navigationEvent on bottom tab select

* rebase fix

* Emit commandCompleted event instead of nativeEvent

* fix native ios commands

* wait show and dismiss Overlay

Both events broke in 104e3f97

We need this constructor to be accessible in order to integrate with CodePush

This reverts commit 5cd2972ca0.

This reverts commit 864a84dfcf.

* feat: support a “modal” prop for tabbed ios apps

* fix: apply temp fix for react-native-navigation#1502 (#1)

* fix: enable fab icon scaling (#2)

* v1.1.340 [ci skip]

* Update FloatingActionButtonCoordinator.java

* Update top-level-api.md

* Update package.json

These two functions were related to previous modal implementation which relied on Dialogs

The reload listener currently doesn't properly pickup reloads from debug menu
