/*
* M Oakley 
* Set the last breadcrumb.
*
* Rules:
* If there is top nav on the site:
* - If there is a left nav in the On state, display the top nav as the breadcrumbs hyperlinked.
* - If there is no left nav in the On state, display the top nav as the breadcrumb unlinked
*
* If there is no top nav on the site:
* - If there is no left nav in the On state, don't add a breadcrumb at all (ie. remove the #lastcrumb)
* - If the current page is a top level left nav, and is On, display it in the breadcrumb, but not hyperlinked
* - Otherwise, display the hyperlinked 1st level nav in the breadcrumb
