State saving should save the current playlist, search, etc.

[Cassidy James Blaede]

How to reproduce:

1. Play a song from a custom playlist.
2. Pause the song and close Noise.
3. Reopen Noise and hit play.

What should happen:

* Noise picks up where it left off, playing songs from that playlist.

What actually happens:

* Noise picks up that _song_ where it left off, but then continues to play a new song in the whole library rather than one from that previous playlist.
