- Patch #19451 by JonBob: improved consistency of module descriptions.  We should write guidelines for this -- maybe in the PHPDoc code of the _help hook.

  * split up the menu callback for editing/adding/deleting rules
  * improved the delete message
  * fixed a double page printing bug

- Clean URLs: search/type/keywords e.g. "search/node/drupal release". The search
  form is POST submitted, but drupal_gotos to a GET page. This makes it easy to
  copy/paste search URLs, and makes the pager a lot cleaner.

- Remember the search keywords when switching between the search tabs. This is
  done through the same GET URLs rather than the session, so it does not mess up
  between multiple browser tabs.

- Report which keywords were ignored because they were too short.

- #820: Provide search block

- Treat multiple wildcards in a row as one

    - permissions menu link updates in a number of modules help
    - anchor link fix in distributed auth help
    - "my account" link fix in user help
    - spelling correction in tracker.module help

- I also changed 'admin/access/perms' to 'admin/access/permissions'.

- Patch #16246 by Moshe: added mechanism to direct the user back to the referring page after completing a form.
  (Moshe: the patch against node.module failed to apply.)

- Patch #16358 by James: added toolkit to enable better image handling.  The avatar code and the upload module have been updated to take advantage of the new image API.

There are 5 main functions that modules may now utilize to handle images:

* image_get_info() - this function checks a file.  If it exists and is a valid image file, it will return an array containing things like the pixel dimensions of the image, plus the 'type' and common extension.
* image_scale - resizes a given image to fit within a given width / height dimensions, while maintaining aspect ratio (not distorting the image).  This function can be used to generate thumbnails, or ensure a maximum resolution, etc.
* image_resize - similar to image_scale (but will not respect aspect ratio - may well distort the image).
* image_rotate - rotate an image by X degrees
* image_crop - crops an image to a given rectangle (defined as top-left x/y coordinates plus a width & height of the rectangle).

Contribution modules will now be able to rely on these base manipulation functions to offer additional functionality (such as image nodes, photo galleries, advanced image manipulation, etc).
