Add NinSnesVersion for future updates. Update enum names since they are unscoped. (VC11 will allow us to use scoped enumeration, but here we use VC10 at the moment.)
Update NinSnesScanner. It now starts using the most basic part of nintspc's scanning routine. VGMSeq conversion probably will not work good until I do some fixes in NinSnesSeq. The format is too complicated!
