   Content handler for requests for: /adm/wrapper/...
   used for content to be displayed in an iframe, or launched in a separate tab
   or window via a link.  The target URL is extracted from the requested URL, by
   removing the /adm/wrapper prefix. 
   
   The target URL will typically be a PDF served from the current server, an 
   external resource URL served from a different server, or an external tool
   (from an LTI Provider) launched from LON-CAPA (as LTI Consumer) and launched
   via a link.
   
   If the request included forceedit in the query string, and the requester has
   rights to modify course content, then the editor will be didplayed to allow
   changes to be made to the resource (e.g., change the URL of the external resource,
   or change the setting for the external tool instance.
   
   If not in edit mode, then the wrapper() subroutine will be called to generate the
   standard LON-CAPA inline menu, and then either a link to launch a separate tab or
   window, or an iframe to display the content inline.
