Library: mark titles that are downloading

While the Library is visible it reads the Radarr and Sonarr queues (on
opening, every 10 s, and shortly after a grab) and matches them to the
titles by movieId / seriesId. Those titles get a blue dot instead of the
green or grey one, and their details say how far the download is.
