// @description Allows control over the way Turkopticon ratings are presented
//              on a forum. This script allows the user to show TO ratings images
//              while images are turned off for the forum, replace all the
//              of the different ratings symbols used with one symbol, show all
//              TO ratings as images only, and show all TO ratings as text only.
