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] Don't tab-complete namespaced commands if send-namespaced is
false
Tab-complete packet is supposed to tab-complete args for commands, but
it also can suggest commands like in version 1.12.2 or lower.
This patch prevents server from sending namespaced commands when player
requests tab-complete only commands.
