   #   PushFile:  Called to do an administrative push of a file.
   #              - Ensure the file being pushed is one we support.
   #              - Backup the old file to <filename.saved>
   #              - Separate the contents of the new file out from the
   #                rest of the request.
   #              - Write the new file.
   #  Parameter:
   #     Request - The entire user request.  This consists of a : separated
   #               string pushfile:tablename:contents.
   #     NOTE:  The contents may have :'s in it as well making things a bit
   #            more interesting... but not much.
   #  Returns:
   #     String to send to client ("ok" or "refused" if bad file).
