Converts giant and fat.gfycat.com hyperlinks to their HTML 5 video counterpart.
This script will alter giant.gfycat and fat.gfycat gif links on reddit and change them to the HTML5 version. This way, when you click the link, you are already going to the HTML5 version without needing to be redirected. I have other scripts that DO redirect, those versions are for links outside of reddit or the browser (Skype, etc.)
