The CSS "Ready Classes" are new additions to the upcoming 1.5 version. They're not available in the 1.4.5 release that you're using. You can download the stable release candidate from the downloads page and use that if you would like.
If you don't want to upgrade to the 1.5 release candidate version right now, you can copy the ready class styles from the link below and add those to your theme stylesheet. Then you can apply the classes to your field as described in the documentation.
You can refer to the FAQ page for a CSS snippet to remove the list bullets.
