Allow playing a track from a starting position

Like the Web API already allows, it would be great to allow playing a track from a starting position.

This feature would improve experience in the following use case:

1. an app allows playing a track from any starting position
2. as things are, when the user starts a track from a position that is not the start of the track, we need to call play() first, then call seekTo() in the result callback. The problem is that often the user will briefly hear the beginning of the track before that jumps to the requested position.

@spotify this functionality is really important to our app. The song briefly playing in the beginning is really messing things up for. Would be eternally grateful if you could have this fix to be up in your priority list. The WEB APIs already allow this.

I tried messing a little with the AudioManager (mute the audio > play a track > "seekTo" the position > unmute) but to no avail. Having this feature would be really great.
