breaks your Drupal.  Only themes in './themes/subdir' are picked up now.

- Patch #18437 by Mathias: Drupal doesn't allow URL aliases that map to Userland Manila posts since they usually contain the '$' and are considered an invalid URL. This patch allows '$' in an URL and thus an alias.  It also resolves a disparity between the 'allowable characters' of absolute and relative URLs. As far as I can tell, those parts of the regexp should be the same.

- Ignore PHP5's strict warnings for now.  The real solution is to rewrite both xmlrpc.inc and xtemplate.inc.

- Patch #17770 by chx: fixed module_invoke() and module_invoke_all() not to use NULL defaults (bugfix) + removed the limitation on the number of paramaters that can be used.

- Minor code style fixes.

- 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).

- Patch #16513 by James (slightly modified): export categories and enclosures to RSS feeds (and made RSS feeds extensible).

  NOTE: this needs to be documented.

  Goba: it would be nice if one of the core themes would showcase this functionality. ;-)

- Patch #16273 by Jeremy: improved the themability of the pager.

- Patch #16253 by Goba: this simple and straightforward patch adds the ability to define different types of markers (while retaining the old default behaviour of the new and required markers to look the same). Someone with enough time on his hands might be able to partition the new marker to a real new marker and a changed marker (since node_is_new() returns TRUE even if nodes changed, and not only when they are new). This is the base on which the new patch can be worked though.

  Modified the patch to remove some redundant code, to translate strings, and to better use the menu system.

- Fixed PHP5 warning: the $result object in drupal_http_request() needed to be properly initialized using 'new StdClass'.

  (I just installed PHP 5.0.3, no less.  Why don't you?)

- Patch #15976 by Neil: if one single admin modifiable menu item is added then it is not put in the menu table because the comparison is > 1 instead of > 0.

- Patch #14731 by chx: made it possible to rewrite node queries.
