Yet further finely-tuned

- Fixed blocks not updating their neighbors when being assembled into a contraption
- Fixed Stockpile Switch not updating its redstone output when its signal is inverted
- Reduced lag caused by many active nearby soul particles
- The Wither's shield is now immune to potato projectiles
- Fixed potato projectile potion effect weirdness
- Golden Apple potato projectiles can now cure Zombie Villagers
- Potato Recovery will no longer drop Golden Apples that successfully hit an entity
