 /**
  * <!-- START SNIPPET: javadoc -->
  * Renders a submit button that can submit a form asynchronously.
  * The submit can have three different types of rendering:
  * <ul>
  * <li>input: renders as html &lt;input type="submit"...&gt;</li>
  * <li>image: renders as html &lt;input type="image"...&gt;</li>
  * <li>button: renders as html &lt;button type="submit"...&gt;</li>
  * </ul>
  * Please note that the button type has advantages by adding the possibility to seperate the submitted value from the
  * text shown on the button face, but has issues with Microsoft Internet Explorer at least up to 6.0
