The Belt is Lava

- Belts are now being avoided by pathfinding
- Fixed Belt observers not detecting items
- Lowered spacing between moved entities
- Tweaked initial collision shape for diagonal belts, fixes entities not being picked up at certain spots
- Fixed Glass Panes being usable on Belts and Crushing wheels (wall tag)
- Fixed Pulley sections not moving entities properly
- Fixed belt UVs not updating when textureAtlas changes, addresses #24
