Renders a playlist as a card that opens the playlist when clicked, in a new tab on a middle click (useCardLink), with its cover, or a tile of its own colour without one, the playlist categories it is filed under and when it last took a dump. Another user's recent playlist shows an unread dot until it is opened on this device. The card is an <li>, for a <ul>, whose class lays it out: a row in a .dump-feed, a tile in a .playlist-grid.
