Fixes:

A core bug that prevented custom searches from working in non-filter contexts was fixed in Thunderbird 3.0.5/3.1 beta 2.

A core feature was added, beginning with Thunderbird 3.1 beta 2, that allows IMAP filter actions that need the message body to work. This FiltaQuilla version adds support for that term.

Enabling of filter actions and search terms was divided into separate pages to prevent issues with view overflow.

New features:

Custom action: javascript and javascript (needs body)

Custom action: detach attachments from message (requires Thunderbird 3.1 beta 2 or later)

Custom action: Suffix to subject. Previous action "append to subject", which was misnamed, was renamed to "prepend to subject" though existing defined actions will still work.

This revision fixes three bugs:

Fixed: M164 Filter action “Run” fails with second after-the-fact action

Fixed: M165 RegEx search term has no method to add flags like case insensitive

Fixed: M166 Custom search term values are not appearing in customize view
