  * @short The HTML statusbar widget for use with the reader.
  *
  * The HTML status bar is a small widget that acts as an indicator
  * for the message content. It can be in one of four modes:
  *
  * <dl>
  * <dt><code>Normal</code></dt>
  * <dd>Default. No HTML.</dd>
  * <dt><code>Html</code></dt>
  * <dd>HTML content is being shown. Since HTML mails can mimic all sorts
  *     of KMail markup in the reader, this provides out-of-band information
  *     about the presence of (rendered) HTML.</dd>
  * <dt><code>MultipartPlain</code></dt>
  * <dd>Viewed as plain text with HTML part also available.</dd>
  * <dt><code>MultipartHtml</code></dt>
  * <dd>Viewed as Html with plain text part also available.</dd>
  * </dl>
