 * methods to be called from XML parsing routine, adds some additional
 * processing and checking, and calls corresponding methods of
 * <code>ThreadXML</code> and other neccessary classes in order to perform
 * the actual creation of a thread, as well as other related items (like
 * favorite threads and thread watches).
