Within content pages the Next and Previous links are not wired up

Fix the Content page markup to ensure that the next/previous anchors correctly navigate between the related content pages.

Example of sectors.html
<ul class="new-article clearfix"> <li><a href="#"><span class="fa fa-angle-left"></span> &ensp; &ensp; &ensp; &ensp; Previous Sector</a></li> <li><a href="#">Next Sector &ensp; &ensp; &ensp; &ensp; <span class="fa fa-angle-right"></span></a></li> </ul>
