Player: Logged in other Location improvement

[Mcayear]

Implementation: When the player is already logged in, reject the player who later logs in with the same name.

Hope to add this item in server.properties.

If the player is logging in from the same IP we should be replacing the old connection not rejecting the new one. I believe this is already the behavior of Nukkit.

Can you provide a configuration option in server.properties so that the server can reject new connections logged in with the same name without closing old connections.
