merge to custom htmpl file modifications when apply webengine patches to Service Desk

Idea created by Chi_Chen Employee on Aug 5, 2011

    currently when a Service Desk webengine patch installs some htmpl files that are customized in the site\mods
    directory the Service Desk administrators would need to manually recustomize the customized htmpl files based
    on the files from the patch. This adds a lot of maintenance work as many webengine patches would need to be
    If the patch install can automatically merge the changes to the existing customized htmpl files, that would be great.
