// Version 4.0: 2015-05-25 - Rewrote script so it works with the Modern theme.
//  Also now works with plutor's MeFi Deleted Posts greasemonkey script
//  (i.e. fish icon appears in deleted posts on front and index pages).
//
// Version 3.0: 2014-05-23 - Changed script URLs to point to greasyfork.org,
//  since userscripts.org hasn't been stable recently; replaced @namespace 
//  with script home page. BTW the profile preference option on MeFi has since
//  been relabeled "Use secure browsing" (from "Use SSL everywhere").
//
// Version 2.0: 2013-07-03 - Now works with the new "Use SSL everywhere" user
//  profile preference for logged-in MeFi members.  Also added support for
//  automatic script updates, as well as better compatibility with Chrome.

// Original fish image design created by Everaldo Coelho and YellowIcon.

// This script was inspired by a MetaTalk comment from yellowbinder:
