Render stress test with 3D models fork mod

Introducing SkinClonesContainer to support draw-call batching with animated skins! By using a lower-LOD skeleton (eg. 10 rendered joints instead of 20+ joints in this example), draw calls can be reduced to 25% of the original. This works great for quickly batching any organic skin (eg. birds, sharks, etc.) without having to manually set up custom joints per clone. Currently, the fully-polygoned model is used without any LOD, only LOD for bones.
