iOS 1.0.1: mini player, Now Playing spacing, play spinner fix

- Mini player floats as a solid card and every screen leaves room for it,
  so it no longer covers the bottom of lists
- More space between title and scrubber; panel switches animate
- Play button no longer spins forever after changing tracks: the engine
  now always reports buffering on load
- Springier button presses and play/pause symbol transitions
