Set ordering of the menu items programmatically.

See plusjade/jekyll-bootstrap#42

I had to temporarily hard code in menu items.

I'd prefer to have something like this back in place

            <ul>
            {% for page in site.pages %}
              <li>
                <a href="{{ page.url }}">
                  {{ page.title }}
                </a>
              </li>
            {% endfor %}
            </ul>
