Mob AI Tweaks

-Brushes can now be used to groom animals, making them drop items occasionally. (For example, chickens drop feathers, turtles drop scutes, most drop string)

-Turtle helmets now function as hard hats, significantly reducing damage taken from attacks that would normally damage your helmet (like falling blocks and kinetic damage).

-Striders can now be fed warped fungi to make them temporarily rideable and controllable, even without a saddle and warped fungus on a stick.

-Animals now causes other animals of the same type to panic when hurt.
