Option for unique player colors
Similarly to forcing player colors, it should be possible to assign each enemy player unique colors client side. To prevent an unfair advantage, a player using this option should show up as e.g. bright green to others similarly as a player forcing colors has to use the forced color himself.
This would reduce confusion in LMS (and other modes with temporary aliances) when two players share the same color or when they change it mid-game.

server alias should be renamed or removed since it's misleading (it doesn't assign unique colors).
