- Patch #168028 by dvessler, merlinofchaos, pwolanin et al: both theme functions and templates may need include files. Flush your caches.

- Patch #145218 by profix898, bennybobw, Crell, forngren et al: use href instead of @import for CSS.

#166593 by hswong3i: move literal values out of some core queries to support cross-database compatibility (ie. better SQL parsing and altering options)

#168587 by jjeff: add rel=nofollow attribute to anonymous comment home page links to counter some spamming

#164122 by merlinofchaos: properly convert underscored to dashes, when constructing template file names matching hook names

#159804 by myself: closure should be filled last, so we have a predictable place to collect queries and strings used on the page

- Patch #141730 by Earl: allow theming system to use wildcards.  I promised in the issue that this patch would still go in, so here goes.

#141725 by Crell and dvessel: allow themes to define multiple CSS and JS files in their .info files, which can be clearly overriden

#146386 by kbahey: refactor 'submitted by user - date' themeing and make it more verbose to translate

- Patch #153535 by traxer: according to the XHTML1 Strict specification, it is not allowed to generate empty <tr></tr> tags.

- Patch #137211 by merlinofchaos: move theme information to .info files and improved theme inheritance.

#127539: progressive operation support, refactoring update.php code to a generic batch API to support runnning operations in multiple HTTP requests
  - update.php is already on the batch API
  - node access rebuilding is in the works
  - automatic locale importing is in the works

 Thanks to Yves Chedemois (yched) for the good code quality, very wide awareness of issues related to batches,
 and the fantastic turnaround times. Hats off.

- Patch #137415 by slantview: simplified the cache API/usages, and made it a tad smarter.  Makes it easier to program for, and easier to replace.  Will need to be documented.

- Refactor partial-page handling for the maintenance page. It's an exotic quirk for update.php and belongs there.

#105726 by moshe weitzman. Remove necessity to hard-code theme engine directories since they can change.
