App 2.45.0: now playing on the Overview

Browse Source 
NowPlayingWatcher follows the head unit's media sessions (listening
only, never connecting to a player); NowPlaying picks what plays and
cleans the text. Tiles shows source, title, artist, cover and progress
under the battery; Halloween carves title and artist into the hill.
Settings: "Show what's playing", on by default. Nothing is logged or
sent.
