- fixed HTML typo in search.inc which confused Mozilla - thanks Carl and
  Keith.

- Changed the authentication and login scheme as discussed on the mailing
  list.
- Fixed the export function in book.module (patch my Julian).
- Fixed the comment alignment (comments got truncated).

- format_username() now takes a second optional parameter which gives the
  real name of the user.

Rest
- updated the calls to format_username() where appropriate to show the name
  of the user instead of the account id. Clicking on a name will still give you
  the account info etc. If you find a place where the real name is not shown
  let me know.

- XHTML-ified search-related code.

- Removed includes/timer.inc: it has been integrated in common.inc.

- Fixed a bug in node.php: UnConeD forgot to update 1 node_get_object().

- I changed the look of theme_morelink() a bit: it might not look better,
  but at least the output is "correct".

- Various small improvements.

- 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.

- Code review: improved search API, tidied up the search related code,
  and fixed a tiny bug when searching for users.

- 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!".

A lot of small changes (search-n-replace) make a big commit:

  - fixed update bug in book.module
  - provide a log message when both adding and updating book pages
  - all configurable variables are now accessed through "variable_get()":
  - rewrote watchdog and submission throttle and removed watchdog.inc
  - improved robustness of sections.inc
  - imporved story.module
  - updated ./database/database.sql

- fixed issue depricated call-by-reference issues
- fixed small visual glitch in includes/function.inc
- changed SQL tables around a bit to be more consistent
  (result: small changes to a lot of different files)
- improved robustness of includes/node.inc
- improved output of cron.module
- improved output of node.php

- large commit of everything else that has been queued in my backlog:
  it's not 100% stable yet

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

- initial import of the preliminary translation code.
- added timer.inc for benchmarking purpose
- bugfix for php-clean
- bugfix for account.php
- removed redundant format_data
- ...

- a 2nd batch of various updates
