/**
 * This script was (heavily) based on the great work of Cryosis7 [926640]
 * https://greasyfork.org/en/scripts/393632-torn-custom-race-presets
 *
 * Using hard-coded presets is still supported but not needed anymore as in game saving is now possible.
 * Any races hard-coded can't be disabled from the script. All fields in the template are optional.
