Goal of this PR
It fixes an exploit: malicious clients created multiple CNetObjPlayer instances, and when teleporting away, the reference to the player's PlayerInfo was lost because they left their CNetObjPlayer clones in the same place, causing nearby players to crash because they didn't have a valid pointer to the PlayerInfo from those "clones".
How is this PR achieving the goal
Not allowing clients to create more than one CNetObjPlayer.
