Ignacio Etcheverry 9421da57ad C#: Add 'Singleton' property to singleton wrapper class
This property returns an instance of the singleton.
The purpose of this is to allow using methods from the base class like 'Connect'.
Since all Godot singletons inherit Object, the type of the returned instance is Godot.Object.
