* Show the content list window with a given set of content * @param cv the content to show, or nullptr when it has to search for itself * @param type1 the first type to (only) show or #CONTENT_TYPE_END to show all. * @param type2 the second type to (only) show in addition to type1. If type2 is != #CONTENT_TYPE_END, then also type1 should be != #CONTENT_TYPE_END. * If type2 != #CONTENT_TYPE_E

 *   If type2 != #CONTENT_TYPE_END, then type1 != type2 must be true.
