Title: Bug Fixes in Models

* fix crash in rendering when the animation URL is bad or contains no frames

* fix case of not rendering models when there are models in a parent tree element, we weren't recursing down into the children.

* fix case where we wouldn't mark the octree path as dirty when a model was first added, only if it was edited.
