File Apple's Football and Soccer under Sports in the Directory (#125)

The Directory listed Football (6 feeds), Soccer (7) and "Soccer," (2) as categories of their
own beside Sports, and Software How-To (2) beside Technology. CATEGORIES spelt two of Apple's
Sports subcategories American Football and Football (Soccer), names no feed uses: Apple's list
says Football and Soccer, so a feed naming either fell through as a category of its own.

They are Apple's spelling now. The old spellings are aliases, since Jev picked from the list
while it had them and its answers are stored, and so is Software How-To, Apple's Technology
subcategory before its 2019 list. A comma or full stop at the end of a feed's category, as in
"Soccer,", is dropped.

 ### Fixed
 
+- Feeds that file themselves under Apple's Football or Soccer show under Sports, and those under the old Software How-To under Technology, instead of as categories of their own.
 - The download queue, in `ipx status`, `/api/status` and the dashboard, counts only what iPX will download on its own: older episodes beyond a show's limit, and files of feeds that do not download automatically, are listed but no longer counted as waiting.
 - Artwork published on http is stored on https when its host serves it there, so the page loads it directly; the rest still comes through iPX.
 - An iPhone adding the site to its home screen finds the icon at the first address it tries.
