CameraHelper: make it usable outside of the Camera

[antongit]

Is your feature request related to a problem? Please describe. There is a process node CameraHelper (Advanced) that visualizes a Camera. It is used inside the Camera node, but it's impossible to use it outside of the Camera, because it's having only its State output, but the Class itself is marked as Internal. Now it's possible to visualize Cameras only in F4 mode, but what if I want to see my cams in other scenarios?

Describe the solution you'd like I guess it will be good to have everything in the Render operation as a Processnode, like CameraHelper (Core) or something. Then this processnode will be usable for everyone: Camera > CameraHelper > RenderEntity
