Mob AI Tweaks

-Added slimer zombies. These are zombies that spawn holding little slimes which shoot high-knockback slime balls.

-Added a rework to silverfish.

-Added fireworks_boost_mounts config. This makes it so that when you are riding a mount, you can right click to use a fireworks rocket to boost that mount. Grounded mounts will levitate, allowing you to let them climb up hard to reach places, but keep in mind this is costy and hard to control.

-Animals can now be fed with chorus fruit to forcibly teleport them out of danger.

-Fixed husks killing whatever is riding them when burrowing. Now, the riding mobs are given temporary invincibility unless the husk was hit by another entity.

-Fixed zombie dads making door breaking sounds when killed.

-Fixed door zombies being able to spawn from mob and trial spawners.
