Subject: [PATCH] Block Enderpearl Travel Exploit
Players are able to use alt accounts and enderpearls to travel
long distances utilizing the pearls in unloaded chunks and loading
the chunk later when convenient.
This disables that by not saving the thrower when the chunk is unloaded.
This is mainly useful for survival servers that do not allow freeform teleporting.
