- A large batch of updates, amongst them a rewritten node system.  More
  information available on the mailing list.

  easier. Also changed the <? tag to <?php in some cases.

- Merged "system settings" and "module settings" into one page.  IMHO
  it wasn't a good idea to split them up in first place, and it turned
  out to be quite hard to decide where to put some variables.

  Also moved some variables around and even renamed a few variables
  while doing so.

- Added a page_header() and page_footer() to all top-level .php pages.

- Redid settings.module and even renamed it to conf.module.
    * Settings are now grouped in basic categories like "system
      settings", "module settings" and "filters".
  * Added new settings to make Drupal easier to configure and
  to make some aspects like the watchdog scale better.

- Renamed includes/settings.php to includes/conf.php.

- Added filter support to conf.module and introduced filter hooks so
  modules can implement and export new filters.  Example filters are
  an HTML filter (implemented), a profanity filter, an url converter,
  ASCII smileys to images filter and so on ...

- Reworked the check_* functions: user contributed content/input is
  only verified and filtered once in its lifespan.

NOTES

- Altough this is a large commit, no database changes are required.

- Uhm.  Rewrote the module system: less code clutter, less run-time
  overhead, and a lot better (simpler) module API.  I had to edit a
  LOT of files to get this refactored but I'm sure it was worth the
  effort.

  For module writers / maintainers:

  None of the hooks changed, so 95% of the old modules should still
  work.  You can remove some code instead as "$module = array(...)"
  just became obsolete.  Also - and let's thank God for this - the
  global variable "$repository" has been eliminated to avoid modules
  relying on, and poking in drupal's internal data structures.  Take
  a look at include/module.inc to investigate the details/changes.

- Improved design of the content modules "story", "book" and "node"
  (to aid smooth integration of permisions + moderate.module).  I'm
  still working on the permissions but I got side tracked for which
  I "Oops!".

- improved submit.php:
  it now uses the new category code, incl content bindings.
  You can setup different "categories" which map on a content
  type.  Example:
    review   -> review.module
    article  -> story.module
    column   -> story.module
    announc. -> story.module
    addons   -> file.module
    themes   -> file.module
- "generalised" story.module and book.module's output.
- fixed bug in includes/timer.inc
- fixed glitch in theme example.theme: it said "$how by" but
  the variable $how has never been declared.
- added "drupal development settings" to display some timings
- more work on the categories/topics -> does NOT work yet

- applied David Norman's patch to turn all <?'s into fully qualified
  <?php's.

Yet another large batch of updates:

 - I rearranged some of the code and clean-up some of the mess.

 - Added "blocks" which can be user defined/controlled: check
   to see.  The positioning of blocks is rather basic for the
   moment, so I'm all open for input on that.

- intermediate commit: some bugfixes, changes and some drastic
  changes to block and module support

- a few more updates

- large batch of updates

- added module support and preleminary (read: example) modules
