 Class: PrefsManager

 Desc: Manages all other game data that isn't handled about SongManager, 
	GameManager, or ThemeManager.  Some of this data is saved between sessions,
	for example, input mapping settings and GameOptions.  This class also has 
	temporary holders for information that passed between windows - e.g.
	ScoreSummary.
