#168812 by webchick and pwolanin: in case we have a database error, trace it back to the original database function call, so we can provide a more accurate error message for DB errors

#161107 by fwalch and bragon: actually implement the missing forum_term_load to work behind the %forum_term menu item resolving calls

#57676 by JohnAlbin et al: properly support theme engine and theme specific settings via a theme-settings.php file

#149567 by chx and meba: set install_task variable to 'done' on update, so installer cannot be run on Drupal 6 on an upgraded site

#156475 by Christoph C. Cemper and greggles: actually call the publish op on hook_comment when a comment is first (automatically) published

#165343 by merlinofchaos and dvessel: include path history in theme discovery suggestions, so we find subtheme files properly

#166071 by jjeff and dvessel: move default template preprocess code to template_preprocess, and add *lots* of documentation to template files and functions

small but annoying wording typo noticed by chx: translation_node_get_translations() actually loads partial nodes only

#111127 follow up patchby myself: document the node_load internal cache and external cache, and how they interoperate

#111127 follow up patch by chx, slightly modified: properly wipe the translation set node_load caches when a set is updated

noted by Robert Douglass in his caching presentation: the key param to cache_get should be renamed to cid for consistency (all other functions have cid)

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

#157510 by pwolanin and chx: search module needs menu tail arguments (arbitrary 'directory' looking parts)

#111127 by chx: cache node_load(), so heavy operations loading data from external sources and only invoked once (note that you should do everything dynamic in the view op, not the load op)

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