Polish downloads, settings, and detail titles

Use right/down chevrons in the download manager and order downloaded
tracks by disc and track number, matching the album screen. Move sync
concurrency to the end of the network settings, let the artist hero name
wrap to six lines, and leave the album hero title unbounded.
