Small enhancement in Drupal.popups.formSuccess

I think that there is a better way of content area update. Current method is to temporary inject hidden new content into page body, change old content with new one and then remove hidden content. That works buts its ugly like comment in code already says it.
Better is to create jQuery object from new content on the fly and then query that object and not all page, something like this:

if (isset(options.targetSelectors)) { // Pick and choose what returned content goes where.
  var ajaxRes = $('<div id="popups-temp" style="display:none">'+ data.content.replace(/\n/g, '') + '</div>');
  jQuery.each(options.targetSelectors, function(t_new, t_old) {
    if(!isNaN(t_new)) {
      t_new = t_old; // handle case where targetSelectors is an array, not a hash.
    }
    // Instead of injecting temp content, just query ajaxRes for new content.
    var new_content = $(t_new, ajaxRes).html();
    // inject the untrimmed new content into the page, but hidden - ugly hack!
    //$('body').prepend('<div id="popups-temp" style="display:none">'+ data.content.replace(/\n/g, '') + '</div>');
    //var new_content = $(t_new).html();
    //$('#popups-temp').remove();
    var $c = $(t_old).html(new_content); // Inject the trimmed new content into the original page.
    Drupal.popups.attachBehaviors($c, options);
  });
}

This is cleaner and faster. Tested with 5.x-1.0-beta1 and its working fine.
