00bd087d82 BVH add support for visibility (activation) 
A major feature lacking in the octree was proper support for setting visibility / activation. This meant that invisible objects were still causing lots of processing in the tree unnecessarily.

This PR adds proper support for activation, items are temporarily removed from the tree and collision detection when inactive.

690e07b509 Dynamic BVH for rendering and godot physics 
Complete rewrite of spatial partitioning using a bounding volume hierarchy rather than octree.

Switchable in project settings between using octree or BVH for rendering and physics.
