* In the parser, make -n (impotent) and -a (anonymous) more
  independent. Used to be that -n required -a, but that makes the
  preparse less useful, since it cannot catch project related errors
  (like bad osids, or node type permissions), and so the user does not
  get that until the email message later. Thats so annoying, even Mike
  whined about it.

  Note that impotent mode is sorta misnamed now, since the parse never
  operates on the DB. Rather, impotent mode now skips doing the XML
  output phase (still aptly named updateDB!).

* Add -p (pass) option. I added this for my script that was parsing
  all the old NS files to get renderings. In this case, I do not want
  -n or -a; I want to upload the results into the DB, but the project
  related checks are obviously going to fail since I was doing it
  inside the testbed project. So, -p turns on some of the anon checks,
  and later might be used to turn certain features that are no longer
  supported, since all we really care about is the toplology (some NS
  files failed on old features and syntax).

Upon reflection I think these three options could probably be rolled
into just two, by cleaning up the current impotent and anonymous
flags.
