Documentation of BrettCrumbs.php

Created BrettCrumbs so that I could have a simple breadcrumbs navigation within wiki.

BrettCrumbs provides a simple way of displaying the breadcrumns based on using the "/" character as hierarchy.

So a page http://192.168.1.100/wiki/index.php/Process_Documentation/Software_Engineering_Guidelines would be displayed with bread crumbs at the top:

Home < Process Documentation

Changes to LocalSettings.php

# Added this to get Breadcrumbs navigation
require_once( "$IP/extensions/BrettCrumbs.php" );
