Feed tabs say what they are

Below xl every feed tab but the selected one was a lone icon with no name, for a screen reader or a finger. DTab takes
an AccessibleName, which DTabs renders as the tab's label and tooltip, and FeedTabs names each tab; on a phone every
tab shows its name too. The strip is marked as one that scrolls sideways (data-scroll-x), says it holds the feeds, and
on a phone fades at the edge where more tabs wait (edge-fade-x, a scroll-driven animation where the browser has one);
the selected tab is brought into view when it changes (window.revealActive). Explore's tabs get the same.
