Consul: Navigation sidebar on custom pages

[decabeza]

Background

Now admin users can create custom pages /admin/site_customization/pages and some of this pages have a lot of content.

What we need

Include a new checkbox option to show headings as sidebar navigation of the content to users.

For example, if the page has the following content:

<h3>Title of this section</h3>
<p>Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod
tempor incididunt ut labore et dolore magna aliqua.</p>

<h4>Another heading</h4>
<p>Duis aute irure dolor in reprehenderit in.</p>

<h3>A new section</h3>
<p>Voluptate velit esse cillum dolore eu fugiat nulla pariatur.</p>

The sidebar should show somethig like:

<ul>
  <li>
    <a href="#h3_1">Title of this section</a>
    <ul>
      <li><a href="#h4_1">Another heading</a></li>
    </ul>
  </li>
  <li>
    <a href="#h3_2">A new section</a>
  </li>
</ul>

Notes

Also wrap title and subtitle page content with <div class="jumbo"> to add styles to header.
