Smooth finalizing, rewinding, and a bit more crash safety

* Smooth finalizing of song when loop is disabled (old ugly hack has been removed :wink:)
* Added an ability to reset song position to begin (very helpful when song reaches the end)
* Avoided possible crashes on attempt to fetch sample data without opening of MIDI file
