Mob AI Tweaks

-Added an option to disable miniboss healthbars (rn, only the ravager is a miniboss, so it only disables its healthbar, setting is named ravagers_are_minibosses)

-Added an item blacklist for modded bows and crossbows mobs can spawn with (should be named mob-ai-tweaks_item_blacklists.txt, if it didn't generate, you can try making one then add one # then ENTER as the first character to get it to work!)

-Added an option to let undead horses burn during the day. They do not burn if saddled or ridden by a mob.

-Added an option to disable boss summoning and defeat texts.

-Fixed respawned end crystals being unbreakable.

-Fixed wither flying away bug by capping its maximum y velocity.
