    Add an icon to edited messages
    
    Currently this is using "format-text-direction-ltr" which is a crappy choice.
    We should ask for a better icon. Also, this should really be implemented as
    a class, so that the icon can change with the theme. Or be made part of the
    Adium theme, or something. Basically this is kludgey.
