Added support for 2D shadow casters. *DANGER* Shaders in CanvasItem CHANGED, if you are using shader in a CanvasItem and pull this, you will lose them. Shaders now work through a 2D material system similar to 3D. If you don't want to lose the 2D shader code, save the shader as a .shd, then create a material in CanvasItem and re-assign the shader.
