Fixed user -> user_id transition for enano_tags table

Optimized JS aggressive-compression list a little more

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
