+ AvatarManager & ObjectManager no longer assume each avatar seen is a new avatar, at least for ObjectUpdatePackets -- the other object packets still need to check for existing avatars before adding new ones.

+ Added back in KakaduWrap because the jasper wrapper doesn't support TGA/TIFF to J2C (yet) -- so it's needed for uploads
