work on aligning fog
slight performance improvements - no need to resort dynamic objects into the octree - they should be removed from their node anyway, but still keep the update function. That update function should bail if the object is dynamic. Also, no need to update particles that are invisible
fix character controller error when trying to walk on the ground plane. Recent change to skybox makes it possible for the pick to return nothing. Previously, the ground clamp pick would always at worst return the skybox. Skybox is no longer intersectable, and thus code needs to handle null from pick. Also fixed delete function in painter tool fixes #120
