Show the album cover on a media tile, in the same strip as the live camera pictures (0.2.92)

A single or double-width media player tile takes Display -> Album cover
on a Guition: the cover of what plays in the icon's place, like Home
Assistant's own tile. It rides in the page's strip of 0.2.91: the request
and the answer are the same, a media player is simply among the tiles.
The app fetches a player's picture only when its address changes; a page
with a camera loads at the camera's pace with the cover reused, a page of
media tiles alone loads once, and a new track (the picture's mark in the
state, part of the page's wish) asks again at once. A player without a
picture keeps its icon and is not asked for; the double-width tile keeps
its controls; the tile over the whole page keeps the card's big cover.
Firmware 0.2.78.

 view, and it refreshes while that page is on the screen; a tap still opens the camera full screen. The
 camera tiles of one page share one download, so six live tiles cost the screen no more than one.
