    Move .linked class from buttons to their container
    
    According to gtk's documentation, GTK_STYLE_CLASS_LINKED has to be set
    on the surrounding container instead of on the widgets that should be
    linked.
    
    Also move setting the style classes for toolbar buttons into the .ui
    file.
