NVorbis, AnyCPU support, Unsafe Code removal
#FIX: Fixed a bug where streaming SoundInstances never disposed after being finished.
#FIX: Fixed broken method signatures in OpenTK.
#CHANGE: Now using NVorbis as OggVorbis decoding library.
#CHANGE: Duality and all related projects now compile without unsafe code and using AnyCpu. On 64 bit systems, they should now be able to address all the available memory.
#REMOVE: Removed old, P/Invoke OggVorbisDotNet bindings.
