/* ShowCustomModal
 *
 * $.showCustomModal brought to UCP without polluting the jQuery global
 * QoL updates include:
 * - Let you pass the options as the 2nd argument instead of 3rd, with `content` replacing the content
 * - closeModal functions now properly handle multiple inputs
 * - Buttons don't need an id not to have id="undefined"
 * Pain points not addressed:
 * - Body class .modalShown still unstable if more than one modal shown at once, don't rely on it
 * - Ugly code inside
 *
