Test PR of lazy load of ghosts and scene streaming

Browse source 
For now scene streaming only affects how subscenes are loaded. If you try it on everything in a scene expect issues as the namespaces are not linked up at that point.

This is a TEST! Do not merge! If you do you will open up a gate to an alternate reality where all that you believe will cease to exist in an endless void of darkness.
