/** Attaches a simple {@link com.kotcrab.vis.ui.widget.color.ColorPickerListener} implementation to the picker. Expects
 * ID of an action that references a method consuming a {@link Color}. The method is called each time the color is
 * changed, reset or approved. If you need to attach a more complex listener, you can provide your own implementation in
 * Java after getting reference of the picker with
 * {@link com.github.czyzby.lml.parser.impl.attribute.OnCreateLmlAttribute} or
 * {@link com.github.czyzby.lml.parser.impl.attribute.OnCloseLmlAttribute}. Mapped to "listener".
