Simple Hostile Despawn

In vanilla Minecraft, hostile mobs that pick up items or enter boats/minecarts become persistent, accumulating over time and causing server lag.

Simple Hostile Despawn restores natural despawning for these mobs. When a mob with picked-up loot despawns, its collected items are safely dropped onto the ground.
