Adds name/appearance bans. They're based on jobban code, but prevent the...

... banned player from using their preset names and appearances.

Also corrects a spelling error (Indentity) in the char prefs panel.

So, I've tested this reasonably thoroughly, unbans and rebans in one round, over multiple rounds, over multiple rounds while flipping between SQL and legacy banning. It seems pretty solid. Yell if I need to update anything. :+1:
