Title: Implementing "Song.FromUri"

As documented in: http://msdn.microsoft.com/en-us/library/microsoft.xna.framework.media.song.fromuri.aspx
This method is implemented so a project can load a song from disc using a relative uri. There are more use cases not implemented but this can serve as a start.
