Bruno Windels 457c096c9b render date separator in base class for all tiles
apart from gap, which doesn't have date

since we add a container when the date separator needs to be shown, and
we don't want to rerender the whole tile, we always render timeline
tiles with a DIV rather than an LI (same for the UL).
