kwiberg 5a25d9504a FileRecorder + FilePlayer: Let Create functions return unique_ptr
Because passing ownership in raw pointers makes kittens cry.

This also means we can ditch the Destroy functions and the protected
destructors. (Well, almost. We need to keep the old CreateFilePlayer
and DestroyFilePlayer around for a little while longer because of an
external caller.)
