Improved the warning dialog

[Danielle Foré (danrabbit)]

* "Restore to default settings" -> "Restore Default Settings" and remove destructive action class

To fix dialog margins and padding:

    layout.set_column_spacing (12);
    layout.set_margin_right (6);
    layout.set_margin_bottom (18);
    layout.set_margin_left (6);

    dialog.border_width = 6;
