    preferences-dialog: Remove GtkHButtonBox
    
    This button box has a single child, a GtkButton, and
    is effectively only used to horizontally align the
    button at the end. This property can be trivially set
    in the button itself nowadays.
    
    Remove the GtkHButtonBox holding the "Reset to Defaults"
    button, and preserve the end alignment of the button by
    setting the "halign" to "end" in the button itself.
