Edit WebSubmit Function

This function tries to retrieve in the 'pending' directory or
directly in the documents database, some information about the
document: title, original submitter's email and author(s).  If found,
this information is stored in 3 global variables: $emailvalue,
$titlevalue, $authorvalue to be used in other functions.  If not
found, an error message is displayed.

Parameters:

     * authorFile: Name of the file in which the author may be
                   found if the document has not yet been
                   integrated (in this case it is still in the
                   'pending' directory).

     * emailFile: Name of the file in which the email of the
                  riginal submitter may be found if the document
                  has not yet been integrated (in this case it is
                  still in the 'pending' directory).

     * titleFile: Name of the file in which the title may be found
                  if the document has not yet been integrated (in
                  this case it is still in the 'pending'
                  directory).
