Scene managment system

Every minigame scene is loaded one after another with the loadNextScene() function.
This function is implemented independently in each minigame main script.

Eg:

func loadNextScene():
	var currentScene = get_tree().root.get_child(3).get_child(1)
	var nextScene = load("res://scenes/shopping.tscn").instantiate()
	get_tree().root.get_child(3).add_child(nextScene)
	get_tree().root.get_child(3).remove_child(currentScene)
	currentScene.queue_free()

The plan is to create a global scene handler.

2 possible ways i see :

Create a loadScene(scenePath) function
Create a queue of scenes and a function loadNextScene() that gets the top of the queue and loads it

The scene handler could use a signal so that minigames can notify when to load the next scene.

Files impacted :

cutMirror.gd
meltSand.gd
painting_canvas.gd
runeGame.gd
smashGlass.gd
start_scene.gd
shopping.gd

A crash appears when using the builtin function change_scene_to_file()

Invalid assignment of property or key 'stream' with value of type 'AudioStreamMP3' on a base object of type 'previously freed'.

The root cause seems to be an audio stream that is not freed properly in shopping.gd:64

The audio players were children of PauseMenu node, contained by the gameInterface node that was a child of the startScene, once the startScene got freed when switching scenes, the audio players too, hence the error, this is fixed in 91badf90cc
