Ceon URI Mapping V5.0

[torvista]

Regarding merging to ZC157.

The ZC157 version of admin javascript loader will pull in files per page.

In lieu of a complete rework to use the plugins framework, in admin I moved ceon_uri_mapping_javascript.php to the /javascript folder, and added two files to be auto-included by javascript loader per admin page:
categories_CEON.php
product_CEON.php
both with the same code:

<?php 
include ("ceon_uri_mapping_javascript.php");

So avoiding any core file changes.
