"view upload files" permission check

If the "view upload files" permission is disabled for the active role (anonymous or logged user), the FileRequest module doesn't check this permission. This is a critical bug especially because this module try to fix the standard Drupal way for managing files.

I've a simple small patch for correct this bug.

the code in the function _filerequest_download() is inserted in a "if block":

if (user_access('view uploaded files')) {

 [ .... original FileRequest code .... ]

} else {
   drupal_access_denied();
   return;
 }
