/**
 * Update from CCM version 6.6.1 to 6.6.2 where loader has been refactored to
 * use (new style) applications in package com.arsdigita.web instead of old
 * style applications using com.arsdigita.kermel.[Package* & SiteNode].
 *
 * Affected are the packages  CMS Workspace and Service. They are now loaded
 * using new style application classes Workspace and Service.
 *
 * The task at hand is to add the necessary table entries for CMS Workspace and
 * Service to the tables application_types and applications using the
 * information already existing (by old style initialization) in
 * apm_package_types, site_nodes, and apm_packages.
