Build 310: the player slims down, and it can read along with you

[briarrrn]

Build 310 is on TestFlight now.

The audiobook player is quieter. The buttons above the scrubber are down to one. Download lives in the bottom bar, and its caption tells you what it's doing: "Download", then the percentage, then "Downloaded". The "File 3 of 12" pill is now a plain line of text. AirPlay left the player; the Lock Screen and Control Centre carry routing. The Chapter/Book selector is still there, just hidden until you touch the scrubber. It fades in under your finger and stays for a couple of seconds after you let go.

Read along with the narration: if an audiobook's ebook is in your library and downloaded, a small quote button sits on the cover. Tap it and the artwork flips to the sentence being read, four lines at a time, sliding up smoothly as the narrator moves. Tap the words to open the full book at that sentence; tap the picture button to bring the cover back. The listening happens on your device, and nothing you play is sent anywhere.

Community ratings from your metadata providers now show on the book page.

I'd especially like feedback on the read-along text: do the fades look smooth while it moves, and does the scrolling glide? Please update and let me know how it goes.
