* This method is called when the Scene boots. It is only ever called once.
*
* By this point the plugin properties `scene` and `systems` will have already been set.
*
* In here you can listen for Scene events and set-up whatever you need for this plugin to run.
* Here are the Scene events you can listen to:
*
* start
* ready
* preupdate
* update
* postupdate
* resize
* pause
* resume
* sleep
* wake
* transitioninit
* transitionstart
* transitioncomplete
* transitionout
* shutdown
* destroy
*
* At the very least you should offer a destroy handler for when the Scene closes down, i.e:
*
* ```javascript
* var eventEmitter = this.systems.events;
* eventEmitter.once('destroy', this.sceneDestroy, this);
* ```
*
* @method Phaser.Plugins.ScenePlugin#boot
* @since 3.8.0
