Cables & parts and Baking pipeline

- Added cables & parts rendering.
- Facades got a completely new way of rendering. Anvil facades are
totally a thing.
- Added baking pipeline for simplified, highly configurable quad baking.

NOTE: Yes, there are a lot of improvements to do, bugs to fix, stuff to
add. I'm just pushing it prior to code structure change, so it does not
get lost in stashes. But it actually works!
