Add ability to turn on the debug logging from the client and return the results to the client

[CraigRubendall]

If an end user has a problem, the server administrator can turn on portaldebug to get more detailed logs for the requests. However, this requires admin intervention.

Should we have the ability to pass a debug parameter (similar to stp _debug parameter) on the request and to turn on logging, and to return the log back to the requesting client? How would this happen?

For an update service, the response is already coming back to the client in the formResponse or removeResponse divs on the page. Should we add another div to the page to show the value of that response if the debug flag is set? Show it in a different page?
