// @name          TurkHelper for Steve Fossett
// @namespace     http://www.skateatlas.com/GreaseMonkey/turkhelper
// @description	  v1.06 - Please refresh to the latest if you have an older version. While participating in the search efforts I found the Turk steps tedious. This quick script should make the process smoother by scrolling to the image, defaulting the form to 'No' and providing a keyboard shortcut [Ctrl->N] to submit your analysis. Remember to use your mouse if you find something that requires another look. (See script for version info). Added Ctrl-I to scroll to image container.
// @include       http://www.mturk.com/mturk/*
// @exclude       http://www.mturk.com/mturk/preview*
// @version       1.06
// Version History
//		1.06
//		 Added fix for: [BUG] If you find an image that might have a clue and you start typing a description into the "clarifying comments" area, once you type an 'N' or 'n' the HIT submits itself.
//		 - Alt Keys added to keyboard shortcuts to prevent accidental submits
//		 - Alt->N now submits the hit with a 'No' response
//		 - Alt->I now scrolls to the image container.
//		1.05
//		 - Script is now Captcha aware
//		1.04
//		 - Removed the http://www.mturk.com/mturk/accept* exclusion which prevented the script on just accepted hits
//		1.03
//		 - Added exclusion for non-entry forms
//		 - Switched the scrolling logic to use a static value rather than a known element - change due to new form layout
//		1.02
//		 - Added a keyboard shortcut(N|n) to fire the submit button on the form
// 		1.01  
//		 - Fixed the include filter so it would work on /mturk/submit pages
//		 - Added an exit condition if Steve's name isn't found on the page
