Draggable Nodes

This page is a WIP.

• Add DraggableComponent node as child to the Control, Sprite2D or AnimatedSprite2D you want to drag.
• Add DroppableComponent node as child to the Control or Node2D you want to act as a container.
• DragManager.cs needs to be in the scene tree somewhere. Maybe you want it as an autoload, maybe you want it only where you need it.
• Define your own logic in dragManager.CanDropInContainer and dragManager.CanDrop
