Fixed bad ALTER command in PostgreSQL 1.1.2 -> 1.1.3 upgrade

Fixed language string loading in upgrader

Fixed another bad tinyMCE reference in editor.js

Added Gravatar support! And it's really configurable too.

Added "default" option for getConfig() and made setConfig() only set if the new value is different

Oops, somehow changed mysql_query() to pg_query() in MySQL DBAL

Fixed undefined group_rank_id in sessions

Fixed missing require() on search.php in rebuild_page_index()

Got the installer working. Fixed a few bugs including a nasty-to-debug issue where the lang_id was being hardcoded during installation, resulting in strings being inserted with the wrong lang_id causing an infinfinite loop with fetch() throwing a "no strings" error and using template (which calls fetch()) to complain

Fixed lack of str_replace() to runtime-patch cache_anon_sidebar

Got user registration working with the new componentized JS framework

Completed work (we hope) on CacheManager admin page

Made CLI version of common load cache manager properly

Sprited icons for admin panel applets

Fixed gzip output - no longer depends on ob_gzhandler(), uses gzencode() now with a failsafe available if gzencode() is not available. Public function gzip_output() remains unchanged.

Fixed a few places where page metadata cache should have been purged (there may be a few more commits like this)
