Update to How to write a node module http://drupal.org/node/188

1. Title should be HOWTO: Write a node module

2. API has moved. I recommend putting links to 4.6, 4.7, and HEAD. Copied below:
http://api.drupal.org/api/4.6/file/developer/examples/node_example.module
http://api.drupal.org/api/4.7/file/developer/examples/node_example.module
http://api.drupal.org/api/HEAD/file/developer/examples/node_example.module

3. Delete comments. Any comments from 2004 I think can be safely deleted.
Useful tid-bits
'Up to date API documentation' on user ax's site: http://drupal.kollm.org/doxygen/drupal-phpdoc/

Comment 'node_types needed in Drupal 4.6?' and its replies may need to be checked (needed or not).

I am going through pages that link to the old api page... (http://drupal.org/search/node/drupaldocs.org+type%3Abook) I am posting separate issues because it seemed the thing to do, if it isn't, please let me know. Sorry for the extra inbox mail!
