- marvin.theme:
    + small visual improvements

Update of the box function in themes to allow a difference in style/output/look of a box() depending on the position on the page.
Basically this is a 'nice version' of a hack that you could do as a theme author.
I've updated all the standard themes, but 3rd party themes will of course have to be updated by their authors, in the following manner:

- Replace the box() declaration:
< function box($subject, $content) {
> function box($subject, $content, $region = "main") {

- Replace the theme_account call:
< theme_account($this);
> theme_account("region", $this);

Note that you'll have to replace "region" with the correct region that the box is placed in. However if you have a one-column theme, you should use "all", and not for example "left" (if all boxes are on the left).
Usually the "region" here should be the same as the nearest theme_blocks() call.

Those theme authors who want to can make boxes that appear in the center look different from those that appear in the sides for example.

- Fixed annoyance in comment.inc.

Extremely large commit:

- Fixed tiny quote problem in account.php.

- Fixed tiny bug in comment.inc.

- Fixed tiny bug in comment.module.

- Fixed tiny bug in meta.module.

- Simplified user_access() API.

- Rewrote link system: still needs fine-tuning and testing so don't
  upgrade if you are running a production site. ;)

  Updated all modules and themes to reflect this change.  All other
  themes and modules need updating too!

- Fixed bug node.module bug:

    + the node scheduler did not un-schedule a node!

- Fixed comment bugs (as a result of the formification):

    + no signatures where being attached to the comments.

    + check_input was used where is should have been check_output,
      with broken filters as the immediate result.

- Fixed typo in comment.inc as result of form-ification.  Replying to
  a node was not possible: clicking the Preview button redirected you
  the main page.

- Fixed a few tiny bugs in comment.inc (introduced by the form-ification).

- XHTML-ified search-related code.

- Added simple referer module, for sake of fun.

- Made it possible to enter longer username such as 'Gerhard K*llesreit'.

- Updated database.mysql.

- Added a brand-new access.module which allows you to manage 'roles'
  (groups) and 'permissions' ... (inspired by Zope's system).

    + Once installed, click the help-link for more information.

    + See updates/2.00-to-x.xx.sql for the SQL updates.

- Modified loads of code to use our new access.module.  The system
  still has to mature though: new permissions have to be added and
  existing permissions need stream-lining.  Awaiting suggestions.

- As a direct result of the new access system, I had to rewrite the
  way the top-level links in admin.php are rendered and displayed,
  and xhtml-ified admin.php while I was at it.

TODO

- Home-brewed modules need updating, home-brewed themes not.
  (Examples: file.module, trip_link.module)

- As soon we *finished* the refactoring of the user system (KJ has
  been working on this refactoring already) we should consider to
  embed this role and permission code into account.module ...

- Changed '?meta=' to 'index.php?meta='.  Patch by Simone.

- Made it so that usernames can contain spaces.  Like that, people can
  use their full name as their username.

- Modifed form_select() to accept an optional 6th parameter which is appeneded
  to the select tag. $value can now also be an array. This allows for multiple
  selects:
  form_select($header, $name, $values, $options, $help, "multiple=\"true\" size=\"10\"");
- Updated account.module to use the extended form_select() functionality.

- Moved account_password() and account_validate() to user.inc.
- Greatly reduced the number of SQL calls in account_save() when editing an
  account. Now uses one db_query() call instead of 1 + (2 * # of access
  granted).
- Fixed access not being saved when account was added.
- Should now be possible to edit and add accounts. There were certain bugs
  before that would cause odd errors.

- 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.

Oops, a rather large commit:

- Changed meta.module, node.module and index.php to use comma-seperated
  lists of attributes rather then "foo=a,bar=b" lists.  This makes it a
  a lot easier to use both modules.  In addition, error handling can be
  discarded as it can't be made any simpler, really ...

  It fits rather nicely in Drupal's design so I'm getting more and more
  happy with this meta.module (but we are not 100% there yet).

- node.module, node.inc:

   + Improved the node-related admin interface so that navigating back
     and forth the administrative menus is made both easier and faster.

   + Removed some redundant database fields from the node table.  See
     2.00-to-x.xx.sql!

   + Added 2 news hooks called "node_insert" and "node_update".  Just
     like this is the case with the existing hook "node_delete" these
     new hooks will automatically get called when a node has been
     inserted or udpated.  Note that this is an optional call-back that
     only needs to be implemented when required.  With the addition of
     these two hooks, the node mechanism (version 1) is pretty well
     completed.

- watchdog.module:
   + Fixed bug whit the 'regular messages' query in the watchdog.module.

- book.module:
   + Fixed bug in book.module: the 'parent' was not set properly when
     updating a book page.
   + Made it so that older versions of a book page are automatically
     reactived upon deletion of the most recent version, i.e. when
     doing a version roll-back.

- comment.inc:
   + Undid Remco's patch to comment.inc; it does not work in some cases.


- conf.module:
   + Fine-tuned some of the options in conf.module a bit.

- marvin.theme:
   + Visual changes to make it look better on Windows browsers.  Mind
     to give some feedback on this?
   + Fixed 3 HTML typos/bugs.
   + XHTML-ified the theme at a best effort basis; I didn't carry the
     XHTML specification with me.
   + Made use of the theme_slogan variable to display the site's slogan.
   + As soon we have at least one valid XHTML theme we can wonder on how
     to integrate other XML namespaces (cfr. MathML story at drop.org).

- database.mysql:
   + Updated database.mysql so that it contains all the latest "database
     patches".

- Modified comment.inc to use form_*() functions. Might have some
  side-effects I haven't found yet. Report any problems.

- Added a conf option to disable/enable user registrations.
- Added a add account feature to account.module.
- Moved some functions from account.php to account.module.

Todo
- Move most (all?) of account.php to account.module.

  default value instead.

- Added meta.module, an improved index.module that allows you to
  associate different collections - think "combobox" here - with
  different content types, all hardcoded references to "section"
  have been removed and the admin-friendliness of the meta admin
  section has been slightly improved.

  I'll keep working on it during the weekend - if time allows me
  to.  Moreover, I'll focus on the usability/user-friendlines of
  the meta admin section as well as graceful input-checking, and
  error-handling.

  Requires an SQL update, see updates/2.00-to-x.xx.sql!

  Index.module will be removed, or meta.module will be renamed as
  soon we can ditch one of them.  For now, having both coexist is
  not going to harm your setup and is useful to make a comparison
  and / or to migrate from index.module to meta.module.

  Index.module is de-coupled form the rest of the system so you
  will have to use meta.module after having upgraded.  You have
  been warned.

- Updated CHANGELOG.

- Improved watchdog and submission throttle: removed redundant code,
  streamlined the existing code, added new watchdog type called "httpd"
  for Apache errors.  The latter should make it easier to add watchdog
  filters later on.

- Clarified some watchdog messages.

- Fixed typo; missing ".

- Applied Remco's patch:
    the <LI>-bullets were not valid HTML and did only take up space.

- Applied Remco's patch, but added a closing </LI>-tag as well.

- Added missing </TD>.
  (Patched by Remco.)
