- More tab-improvements by JonBob: improved support for the default tabs!

* improves the doxygentation and help text.
* deletes comment_admin and comment_page; using proper callbacks instead.
* related/modified callbacks/menus/functions were tweaked to not use arg() at all.
* the "settings" subtab was weighted to -10 so it'd appear first (in prep of JonBob's local default).
* moderation pages weren't properly showing defined votes or thresholds; fixed.
* when moderation votes or thresholds didn't exist, no error stating as such was shown; fixed.
* we show "submit votes" on the moderation votes page only when votes actually exist.
* fixes the (broken in CVS) comment/reply and comment/edit features.
* fixes the (broken in CVS) "save settings" for comment view options and comment moderation.

In addition I:

* fixed a couple warnings introduced by Morbus' patch.
* fixed a couple translation bugs.
* fixed comment_node_url().

I also found that:

* the collapsed comment views (i.e. 'threaded list - collapsed) are broken.

- Patch #9010 by Morbus: reorganized the order of functions in the comment
  module.

- Patch #8509 by Killes and Steven: added support for sending compressed
  pages.  Useful to reduce your site's bandwidth.

- Made the example theme display status messages.  Not sure why it wasn't.

- Changed the way status messages are printed as per Kristjan's suggestion:
  http://drupal.org/files/issues/error_messages_list.png (issue #9138).

  drupal_set_message() has been changed to group message by type and a
  helper function, theme_status_message(), is added to display the messages.
  Chameleon and Xtemplate have been updated to use this new function.

- Updated CHANGELOG.txt.

- Marked required fields on the node (story, book, page, blog) and comment
  forms using the $required argument of the form_ functions.

- Replaced all Optional's and Required's from the taxonomy forms with proper
  use of the form_ functions.

Please check your contributed modules too!

- Renamed '... your ...' to '... my ...' (cfr. 'my account).

- Fixed colspan in tracker table.

- Renamed '... your ...' to '... my ...' (cfr. 'my account).

- Usability improvement: users can also separate 'list items' (i.e. favorite
  movies) using a comma.  Only few users actually read the form description,
  it seems ...

- Simplified some of the help texts.

- Removed left-over instance of theme('error'): error handling is now done by
  the form code.

- Made the user module's administration form mark required form fields.

- Renamed the blog module's block for sake of clarity.

- Made the blog module's submission form mark required form fields.

- Small improvement to the filter.module's help text.

- Revert patch that accidentically got committed.  Thanks jhriggs.

- Many form_ functions called theme('form_element') with the wrong parameters!

- Fixed order of parameters in form_checkboxes() (plural).

- Patch #9031 by Morbus: this last tracker patch was broken - for installations where the comment.module is turned on, $comments is never set to 0, and posts that have no comments instead get the value of the last successful comment_num_all. The attached patch corrects this ($comments is set to 0 before we do anything) and also merges the if statements.

- Usability improvements: reworked/simplified the timezone/date settings a
  little and made the form groups use consistent titles.

- Usability: improved the error reporting of the file system settings on the
  'home » administer » settings" page.

- Bug #8823: fixed typo: '..' -> '.'.

- I'm removing these files from core: they belong in contrib/docs/marketing
  now (if they are not already there).

- Improved the error/status reporting in Chameleon: made the messages
  stand out a bit better by using green-ish and red-ish colors, resp.
  for 'success' and 'failure'.

- Small change to the way context-sensitive help texts are emitted -
  the pages wouldn't validate in the presence of help texts with
  block-level elements.

- Patch #8975 by drumm: remove block placement preview.  Most themes, if not all the commonly used ones, can handle blocks on either side, and there is no way to see the preview without saving and seeing the results on the site.

  Anything else that can be removed?  Less is more.

- Patch #4166 by daBrado: don't show the profile fields when the user does
  not have the 'access users' permission set.

- Patch #8382 by jseng/junyor: allows autodiscovery of BloggerAPI via RSD.

- Patch #9031 by Ber: if the comment module is not available comment_num_all()
  should not be called.

- Patch #9049 by JonBob: fixed a number of tab issues.

- If you are allowed to vote, results are now shown on a separate node tab "node/id/results".
- Poll voting now submits to a separate URL and uses drupal_goto to go back to the poll node

- Updated node.module to use drupal_goto after submission: this allows people to refresh after submission without any problems.

- Patch by Steven and me: refactored the form handling of nodes. The node system is now using form_set_error() and friends like the rest of Drupal does. This makes for both a consistent user experience and consistent code. It simplifies the forms and validation code, however, it does change the node API slightly:

    * The _validate hook and the _nodeapi('validate') hook of the node API (1) no longer take an 'error' parameter and (2) should no longer return an error array. To set an error, call form_set_error().

    * The _form hook of the node module no longer takes a form hook and should not worry about displaying errors. Ditto for _nodeapi('form_post') and _nodeapi('form_pre').

- Made it possible to edit blog posts and made the blog module use tabs.

- Patch #8952 by Morbus: watchdog module beautifications.

  * slightly reorders the functions in anticipation of http://drupal.org/node/view/9010.
  * reorders help definitions to match the alphabetical nature of the menu items.
  * tweaked visual appearance of menu code (whitespace, etc.)
  * minor tweaks to "warning" help to match style of others.
