This lets VolumeDirectory/DirectoryBlob skip implementing various volume functions like GetGameID, GetBanner, etc. It also lets us view extracted discs in the game list. This ends up breaking the boot process for Wii DirectoryBlobs due to workarounds being removed from the boot process, but that will be fixed later by adding proper DirectoryBlob support for things like TMDs. We now expect the directories to be laid out in a certain format (based on the format that WIT uses) instead of requiring the user to set the DVD root and apploader path settings.
