Fixed bad style update during theme uninstall.

Upgraded to TinyMCE 3.0.3; made editor auto-init again but only on Safari

Fixed $db->die_json(), should now produce standards-compliant output.

Changed TinyMCE init to run only on demand. Highly experimental.

Added modal dialog support for page editor; added customizability for breadcrumbs (thanks to Manoj for idea)

Implemented password reset (albeit hackishly) into the new login API; added dummy window.console object to hopefully reduce errors when Firebug isn't around; fixed the longstanding ACL dismiss/close button bug; fixed a couple undefined variables in mailer; fixed PHP error on attempted opening of /dev/(u)random in rijndael.php; clarified documentation for PageProcessor::update_page(); fixed some logic problems in theme ACL code; disabled CAPTCHA debug

Implemented all security features on theme disabling and ACLs; added clean_key mode to login API to clean unused encryption keys

[minor] fix version number on license block comment in common.php

Oops. Forgot to add the themepreview.png file which is a dummy icon for themes that don't include screenshots. Also in last commit several changes weren't documented, including: Moved several page manipulation functions from PageUtils to PageProcess. Fixed debug message in l10n.js. Started switchover to new rollback API and log_id column replacing time_id as key.

Fixed the fact that cron just didn't work at all (brain fart that day or something)

Modifed EnanoMath layer by segregating it into its own file; got support for big_int PHP extension backend working

Fixed improper serializing of IP that could allow reusing of key from multiple IP addresses.
