 * Slightly modified from standard list; the author & avatar are hidden
 * in CSS. We used to remove them here too, but as it turns out that
 * confuses the inline reply code... and we hide them in CSS anyway
 * since realtime updates come through in original form.
 *
 * Remaining customization right now is for the repeat marker, where
 * it'll list who the original poster was instead of who did the repeat
 * (since the repeater is you, and the repeatee isn't shown!)
 * This will remain inconsistent if realtime updates come through,
 * since those'll get rendered as a regular NoticeListItem.
