Trade: cut Type enum out of AbstractMaterialData class.

Now named MaterialType. It's easier to type this:

    auto t = Trade::MaterialType::Phong;

Than this overlong name, which is moreover ambiguous due to subclassing:

    auto t = Trade::AbstractMaterialData::Type::Phong;
        // or should I use rather Trade::PhongMaterialData::Type::Phong?
