Subject: [PATCH] Added NONE as an option in BufferStorageFlags

None is a desirable option in this enum because it's used much like
BufferUsageHint.StaticDraw for ARB_Buffer_Storage. Using it explicitly
in user code is more clear than 0, and makes it more clear to the
inexperienced author that none is an option.
