This is the "changed since your last visit" marker that you'll
see on ?action=history for a page on your watchlist, marking
edits that were made since you last viewed the page.
updatedmarker is styled by some skins, but not all of them.
I figured it's probably better to style it from history-specific
CSS in core than to fix Vector to style it.
