Get current track position in playlist #359

UseCase:
We use Spotify Android SDK to stream music in our app. Every time user opens the music player, we want to continue playback with the next song in the playlist we selected. If the playlist has 5 songs, and the user closed the player at song 2, next time he opens the player we want to start the playlist at song 3 which is last position (2) + next (1).

Problem:
There is no api to get the current position of the track in the current playlist. Ideally, the track position will be passed within the PlayerState object as is on the web api
