// @description Adds "[BLOCK APP]" link to block (not just hide) apps within the news feed. Automatically blocks quizzes and giveaway spam.

//-------------------------------------------------------
// A note about terminology:
//
// Hiding an app tells facebook to stop showing posts from it in your feed.
// This is roughly the same as removing these items from display using javascript,
// as is done in most facebook greasemonkey scripts.
//
// Blocking an app is substantially different than simply hiding it:
// - block apps cannot gather information about you if you visit their home page
// - block apps cannot gather information about you if your FRIEND visits their home page
// - block apps cannot send you notifications, invites, or mail
//
// This script does not just hide apps. It blocks them. Some of them (quizzes) it blocks automatically.
//
// You should probably visit http://www.facebook.com/privacy/?view=platform&tab=other and refuse some or all
// access to your personal info from apps you have not specifically decided to give this information to.
//
// Changelog (started on version 7, only tracking major changes)
// 03/16/2010 - Updated updater URL.
// 07/28/2010 - Re-hid the blocking iframe. Oddly, nobody mentioned it.
// 07/06/2010 - Yet another Facebook shuffle (they removed the quotes from around the app_id field in data-ft).
// 06/14/2010 - Facebook shuffle accounted for. Also added some more autoblock strings.
// 12/03/2009 - Workaround added for race condition that caused some app stories to be missed if they loaded dynamically immediately after the initial page load.
// 11/11/2009 - Moved iframe to bottom of page as it was not always invisible in all browsers at the top of the page. Added another detection for quizzes. Added update notification. Added sweepstakes detection to autoblocked apps.
// 10/29/2009 - Fix for yet another way that app-generated stories are laid out.
// 10/26/2009 - Revision to keep up with changes to facebook layout. Should be a tad more robust now.
// - Also removes all instances of an app's stories when you block the app. // - Moved the [BLOCK APP] link into the footer of the story as the new hide button was conflicting.
// - Added a few more non-crappy apps to the whitelist and documented them.
//
//
// Technical note:
// When you click on [BLOCK APP] (or a quiz is auto-blocked), the scripts loads the necessary pages
// to perform the block operation in a hidden iFrame. If several apps are blocked in rapid succession, you may
// find your browser lagging for a moment as it performs two page loads per app. This is normal and largely unavoidable.
// Also, the script doesn't maintain a list of blocked apps (maybe in a future version) so if facebook's cache gets in the way and fails to notice you've blocked an app, you may still get stories until the cache is brought up-to-date.
