Now actionsbar.js needs to be included

In RTM the following section in a page will work:

                    <footer id="footer1" data-role="footer" class="revealed">
                        <nav>
                            <ul>
                                <li>
                                    <a href="#" id="addfeed">
                                        <img src="/usr/share/ubuntu-html5-ui-toolkit/0.1//ambiance/img/actions/add.svg" alt="Add feed" />
                                        <span>Add feed</span>
                                    </a>
                                </li>
                            </ul>
                        </nav>
                    </footer>

For vivid, I have to add

    <script src="/usr/share/ubuntu-html5-ui-toolkit/0.1/ambiance/js/actionsbar.js"></script>

This breaks our HTML5 training materials, so it'd be nice to fix this soon if possible.
