Views Accordion should use #attached when adding CSS/JS to the page, rather than drupal_add_js()/_css().

Use case: I have a page callback that returns a render array. Part of its contents are an embedded accordion view. When I use "#cached" in the array to cache all the output, the JS and CSS from Views Accordion doesn't get included on future pageloads, because they're being added via drupal_add_js()/_css() instead of via "#attached."
