Wallper 1.13.1

Playlists change on their own again.

Fixed

• Play starts the playlist's timer. A playlist could stay on one wallpaper after Play until the shuffle button in the bottom bar was clicked too.
• Choosing a wallpaper from the playing playlist keeps it going from that wallpaper, instead of quietly stopping.
• The playlist page shows when changes are paused, and picking a pace resumes them.
