v2.0.2

Fixes the queue's track-change listener.

_wireQueue subscribed to MediaList's current event, which was renamed to item — so emit('item') never fired on a track change and consumers got no track-change feedback. The player warned about it at runtime; nothing acted on the warning because the fix was never released.

Consumers must also take music-player and video-player 2.0.2: both bundle this code into their IIFE builds, so a core bump alone does not reach them.
