Subject: - Made the node forms support "help texts": it is not possible to
 configure   Drupal to display submission guidelines, or any other kind of
 explanation   such as "NO TEST POSTS", for example.

- Added node versioning: it is possible to create revisions, to view old
  revisions and to roll-back to older revisions.  You'll need to apply a
  SQL update.

  I'm going to work on the book module now, so I might be changing a few
  things to enable collaborative, moderated revisions - but feel free to
  send some first feedback, if you like.

- Added some configuration options which can be used to set the minimum
  number of words a blog/story should consist of.  Hopefully this will
  be usefull to stop the (almost empty) test blogs.

- Various improvements:
   + Fine-tuned new node permission system.
   + Fine-tuned the functions in node.inc.
   + Fine-tuned some forms.
   + XHTML-ified some code.
