Accessibility: Template Notices

Validation error messaging. The use of a list allows the user to know how many errors were found.

Be sure to shift focus directly to this div $('.error:first').focus();

Proposed:

<div class="bbp-template-notice error" role="alert" tabindex="-1">
    <ul>
        <li><strong>ERROR</strong>: Your topic needs a title.</li>
        <li><strong>ERROR</strong>: Your topic cannot be empty.</li>
    </ul>
</div>

Current:

<div class="bbp-template-notice error">
        <p><strong>ERROR</strong>: Your topic needs a title.</p>
        <p><strong>ERROR</strong>: Your topic cannot be empty.</p>
</div>
