Suggestion - show user real name in teleport requests

[galacticwarrior9]

If a user has a nickname, this will be used in place of their real name in /tpa and /tpahere requests.

Players on my server are exploiting this fact to kill other players by impersonating people they know; they often do not notice the prefix that is displayed before nicknames. See the suggestion on my server's website here.

I would appreciate it if there could be a configuration option to change this.
