In vanilla Minecraft, when you use the `/teleport` command, you can teleport an entity with passengers to another location.

Bukkit has unfortunately blocked this action, forcing devs to unload passengers, teleport them all, then make them ride again.
This may be simple in some cases, but in others it's not.

I would love to see Bukkit revert the code that restricts teleportation of entities with passengers, or at least add another method like Entity#teleportWithPassengers
