Allow enabling sand duping (#10191)
Because this exploit has been widely known for years and has not been fixed by Mojang, we decided that it was worth allowing people to toggle it on/off due to how easy it is to make it configurable.

It should be noted that this decision does not promise all future exploits will be configurable.

Subject: [PATCH] Fix OfflinePlayer#getBedSpawnLocation
When calling getBedSpawnLocation on an
instance of CraftOfflinePlayer the world was incorrect
due to the logic for reading the NBT not being up-to-date.
