Break all the PRs :(

iOS and Android code base used different naming conventions - this commit aims to unify naming conventions. I probably missed a few properties here and there so this will be an ongoing effort.

* Enabled option was wrongly consumed after it was merged. That meant that the next time SideMenu options were applied, the wrong enabled value was applied
* supportedInterfaceOrientations didn't take default orientation value into account
* mergeOptions didn't save the new options in the ViewControllers current options
* SideMenu always returned the centre ViewController as the current child and didn't take open SideMenu into account

Fixes #5444

When defaultOptions are set after setRoot has been called presenters need to receive the default options as well,
otherwise the outdated default options are regarded.
Fixes #5395

This commit adds initial support for passing null as a valid value for color properties.
When a color property is applied, if it wasn't specified then the default color is applied. Now, when null is passed, no color will be applied
leaving the last color applied as is.

This is useful when showing an Overlay and you'd like to keep the current StatusBar color unaffected. Another usecase would be when you'd like to avoid coloring an icon in BottomTabs.

Add support for dot indicator to BottomTabs.

* Cleanup and reorganise playground app

* Separated tests into three categories
  1. Layouts - layout specific tests and feature showcase
  2. Options - options related tests; interactions between static and dynamic options, merge options etc
  3. Navigation - general navigation features; Orientation handling, events, Overlay etc

* Fixed a few Android bugs
  1. testID wasn’t applied on TopBar react buttons
  2. static options were disregarded when creating initial BottomTab options
  3. Trying to open a none existent SideMenu would result in a crash

* Fix e2e tests

* Fix lint

* Few fixes + split push from SideMenu test into two tests

* Fixes e2e

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.
