Alter LOOC to display character name instead of ckey

[RubberRats]

Did a bit of poking around with this. One possible concern is that messages from mentors/admins will still have their special colors. This is probably fine, but it does limit how useful it is for concealing who you are. Another concern I had was that it makes it way easier to notice that someone has died. If I see John Stafferson in a round and then 30 minutes later see "[LOOC] John Stafferson: lmao" appear above me, I'll 100% know something is up, regardless of if I know who plays them.
