allow webmcp path to be set in cgi script
this allows another script to include the webmcp script when the cwd is not the cgi-bin. the script needs to set the WEBMCP_PATH variable.

9 Calling this function causes the WebMCP to do a 303 HTTP redirect after the current view or action and all filters have finished execution. If routing mode "redirect" has been chosen, then this function is called automatically after an action and all its filters have finished execution. Calling request.redirect{...} (or request.forward{...}) explicitly inside an action will cause routing information from the browser to be ignored. To preserve GET/POST parameters of an action, use request.forward{...} instead. Currently no redirects to external (absolute) URLs are possible, there will be an implementation in future though.
