- wrote more methods to PlayQueue. Now it supports internal history of played items with ability to play previous() item. Also it has equals() to check whether queues has the same content or not
- backstack in fragment is more powerful now with help of PlayQueue's history and able to work great with playlists' PlayQueue and SinglePlayQueue at the same time
- simplified logic inside fragment. Easy to understand. New PlayQueue will be added in backstack from only one place; less number of setInitialData() calls
- BasePlayer now able to check PlayQueue and compare it with currently playing. And if it is the same queue it tries to not init() it twice. It gives possibility to have a great backstack in fragment since the same queue will not be played from two different instances and will not be added to backstack twice with duplicated history inside
