    meldwindow: Remove toolbar style support
    
    I just spent 20 minutes trying to find whether any other applications
    still honoured this setting, and (a) almost nothing I had installed had
    a traditional toolbar and (b) neither of the applications that had
    toolbars actually honoured this.
