This PR removes the selenium browser window for the cheat site jellyneo.  Since we're not interacting with the jelly neo site and we're merely scraping it, I replaced the browser instance window with nokogiri html parsing.  This is lighter weight and also means that now we'll only have *one* browser window open up when running the script instead of two, yay!
