URI translation modified for requests for uploaded files.
Support added for requests for files in /raw/uploaded. Such requests are generated internally by lonnet::getfile() to request a file from the home server for a course.
URI translation to the appropriate file in /home/httpd/lonUsers/$cdom/$cnum. Will also do URI translation to the same path for files in /uploaded, IF request comes from a user session hosted on the home server for the course. For sessions hosted on other servers, URI translation does not occur here, but in the PerlHeaderParserHandler phase (via lonuploadrep.pm).
