codeintel: oop: stop sending the text over on every request
http://bugs.activestate.com/show_bug.cgi?id=101502

Instead, have the codeintel process request the text as needed (based
on the md5sum).  This way, we can avoid looking at the text for requests
that never get processed (e.g. scan document requests).
