Alter LOOC to display character name instead of ckey

[DisturbHerb]

If we do switch to character names in LOOC, I don't think it should be optional. Such a feature shouldn't just be there so that individual people can chooise to hide theirs if they want. The issues that arrive from knowing the ckey behind the character are systemic and cannot be lessened with piecemeal measures, notwithstanding the effect of known static character names on player behaviour.
