    dialog: Remove messageBox container from MessageDialogContent
    
    `MessageDialogContent.messageBox` is not really needed and was only
    needed to show icons, which is now no longer supported. The styling can
    also be done using other CSS classes and this makes it a bit more
    straightforward to add actors to the MessageDialogContent.
