Got an E_NOTICE error from fckeditor_process_form()

Hi there,

To properly develop in Drupal, you should turn on the E_NOTICE on your development machine (See #761780: Plenty of E_ALL notices in modules developed on installation with Drupal tarball.)

I got a notice today and am attaching a patch.

The definition and use of $js_id in the array_merge() looks okay. But I'm wondering... Because later you re-use $js_id many times when it may be NULL. Isn't that part possibly invalid?

          //loop through all enabled filters
          foreach ($enabled as $id => $filter) {
            //but use only that one selected in FCKeditor profile
            if (in_array($id, array_keys($_fckeditor_configuration[$textarea_id]['filters'])) && $_fckeditor_configuration[$textarea_id]['filters'][$id]) {
              if (!isset($fckeditor_filters[$js_id])) {
                $fckeditor_filters[$js_id] = array();
              }
              $fckeditor_filters[$js_id][] = $id ."/". $format;
            }
          }

Thank you.
