Fix inherited eyeball handling for nodes

Introduce the concept of logical and effective global visibility. The
slideplayer can this way check the logical global visibility (which is
based on the eyeball and nothing else) while others can continue using
the effective visibility (that also includes the visibilityTag).

Complete with a simple test scene that allows interactively toggling the
eyeball for some model nodes.
