WiP commit for admin panel localization. All modules up to Admin:UserManager (working down the list) are localized except Admin:ThemeManager, which is due for a rewrite

Merging in something from Nighthawk, can't seem to figure out what

Localized the first parts of the admin panel. As a consequence, also wrote a brand new Admin:PageManager that doesn't suck like the old one did.

Finished localization of SpecialUserFuncs

[Minor] fix stupid bad td width in privmsgs compose interface

Merging in the last couple of revisions from stable

Fixed search indexer causing duplicate keys when two "words" of 64+ characters encountered and first 64 characters are the same (thanks Vadi); attempt to fix onunload confirmation during page editing

Corrected licensing issue on YoungPup's DOM-Drag (it is now public domain -> GPLv2+ for Enano); fixed wrongful access denial under specific circumstances (fetch_page_acl() on nonexistent page + wiki mode)

Made CAPTCHA for guests' page editing work with the non-AJAX interface

Added ability to require CAPTCHA for guests when editing pages (AJAX INTERFACE ONLY)

Replaced TinyMCE 2.x with 3.0 beta 3. Supports everything but IE. Also rewrote the editor interface completely from the ground up.

More localization work. Resolved major issue with JSON parser not parsing files over ~50KB. Switched JSON parser to the one from the Zend Framework (BSD licensed). Forced to split enano.json into five different files.

Fix missing avatar-related columns in users table

[Minor] fix non-localized string in installer (install_stg_buildindex_*); fix wrong string_id in pophelp:url_schemes
