Mob AI Tweaks

-Fixed mobs not being able to use fishing rods.

-Fixed fishing hooks being stuck in the air if the player has the "grappling bobber" enchantment and killed the mob it is hooked to. Additionally, this also fixes a vanilla bug that sometimes causes the fishing hook to freeze in place if the mob it is hooked to dies abnormally (e.g. despawning or sent to the void)

-Added a config setting to change pillagers' crossbow attack range, default value is 15, vanilla value is 8.

-With all bugs fixed, this mod can safely enter beta stages and forge testing.
