- Tidied up node.inc and node.php a bit.

- 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.

 - Locale'd the day-of-the-week-letters. Don't worry, you won't find any "F" or "S" in your locale database, just "Friday" and "Sunday".

 - Fixed a bug with 28/20-day months. Skipping a month ahead from e.g. January 31st would have you end up on March 3rd. Same for skipping backwards.

 - Made the selected date always appear in bold.

 - Prevented all skipping into the future. This was still possible by skipping whole months.

- 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).

- Fixed problem with book.module (reported by Jared).

- Fixed problem with forum.module (reported by Jared).

- Added simple referer module, for sake of fun.

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

- Updated database.mysql.

- Removed conf.module.

- Small but significant improvements to block and box.module which
  makes the ever-confusing "rehash modules" (see module.module) no
  longer needed, hence making module.module redundant.  :-)

- Removed module.module.

- Renamed conf.module to system.module, and added some information
  about the available modules to system.module.

- Various small changes.

- Added locale documentation: written by Gerhard, revised by Dries.

- Added import documentation: written by Gerhard, revised by Dries.

TODO:

- A quick introduction on content syndication needs to be written
  for import.module.

- If some one who is native English could go over the these text,
  please do.

- Made the search result sort from new to old, instead of from old to new.

- Fixed typo in node.php (patch by Simone).
- Fixed type in 2.00-to-x.xx.sql (patch by Simone).

- Fixed bug in account.module (reported by Gerhard and Kristjan).

- Incorporated some of the suggestions.  More to come.

  (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 ...

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

- Fixed small bug in account.php with some usernames not being tolerated.

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

- Fixed small fix in poll.module.  Patch submitted 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.

- 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.

- Removed the default "Your search yielded no results." message as
  suggested by Kristjan.

- block.module:
    + renamed 'overview' to 'preview' as suggested by Kristjan.

- meta.module:
    + renamed 'verify' to 'preview' to make it consistent with
      block.module.
    + fixed comma-bug with attribute list reported by Kristjan.

- node.module:
    + fixed typo: "id$nid" should have been "id=$nid"
