Re-enabled, debugged, and optimized Javascript compression code

Unsuccessful attempt at fixing "dismiss"/"close manager" buttons in ACL editor; non-breaking change to template API to allow plugins to add "normal" sidebar widgets in addition to the special "raw" block type, specified as the third parameter to $template->sidebar_widget(). Defaults to false, which is old behavior; new behavior (enabled by passing TRUE as the 3rd param) means that the content of the block is primarily block-level links.

Fixed version-set on migration code (see the comments in the source for why) and added post-upgrade hooks.

Edit summary should now be carried over when a draft is restored

[Minor] Fixed obsolete trigger upon attempt at page save after draft autosave

OOPS: forgot to add the "save draft" icon

Added "is_draft != 1" where appropriate in SQL queries to prevent drafts from being treated as real revisions.

Added autosave functionality and resurrected the old toolbar code that was added about a year ago but never uesd.

Tagging latest revision as rebrand

Rebrand as 1.1.2; made upgrade framework functional

Added upgrade schema files for 1.1.1 -> current (1.1.2-dev)

Removed unused schema files

Modified editor and rename functions to go through the API when rolling back. This causes rollbacks to be logged.

Mass-fixed all AJAX functions to also check the HTTP status code before parsing the response

Added some basic timezone support; DST support is still to come.

[minor] re-enabled ENANO_DANGEROUS on install.php (oops!); made textarea in page editor focus automatically

Made the form validation icons (check/X/?) more visually appealing. IE-friendliness is still on the TODO list.

Started on a Special:RecentChanges page, more to come.

Fixed some captcha bugs and made all captcha fields case-insensitive

Implemented a new CAPTCHA API; the frontend ($session->{make,get}_captcha) is API-compatible but the backend (the captcha class) is deprecated.

A few hacks to make the 1.1 demo plugin work

Cosmetic improvements to page editor; added demo mode checks in Admin:LangManager

Fixed some MySQL installation schema bugs, thanks to rainmain on the forums.

Added a heading "editing page" in page editor for visual appeal; removed use of alternate <?= ?> syntax in installer as it was causing problems on Win2k3 + PHP/FastCGI. (Experimentally using TortoiseHG's hgtk to commit)

Fixed some stray undefined-variable problems revealed as a result of testing on Windows Server '03, IIS6, PHP/FastCGI, and PostgreSQL 8.2.5.

Fixed splitting bug (really the same issue from stable) in get_pageid_from_url(); upgraded TinyMCE to version 3.0-stable

Fixed jBox menus failing to appear when window scrolled down

Unstable alpha release (1.1.1)

Updated readme file for 1.1.1

Localization is FINISHED, DAMN IT HELLAH YEAH! OVER WITH! Man, it feels to get that off my chest. Release is in under 48 hours, folks. And we're ready for it.
