Accordion functionality for links page

Set up a jqueryui accordion that works with the existing links page markup. To do this, I used wp_enqueue_script('jquery-ui-accordion') in header.php. If there's a better way / place for this include, feel free to put it there. I also had to include the jqueryui css / images for the accordion. The css file has some custom stuff I put up at the top, and you can mess with that to make the style match the rest of the site better.
