Browse the Directory by category, then subcategory, as Apple does (#118)

The Directory had one row of chips holding whatever each feed's category was, a category
(Technology) or a subcategory (Tech News, Video Games) side by side: a podcast's own
<itunes:category> is stored as its subcategory, and Jev's answers (#117) are often
subcategories too, so after the first forced scan the row held 22 chips. /api/directory now
gives each feed's Apple category and subcategory, worked out from Apple's list, and the
page shows the categories, then a picked one's subcategories on a line of their own. A
category that is not Apple's, one an admin typed, stands as a category of its own.
