Title: Fix G3djModelWriter - nodes/parts instead of nodes/materials

G3djModelLoader expects "parts" while fbx-conv wrote "materials" inside node list.

Array> materials = (Array>)json.get("parts");
if(materials != null){
jsonNode.parts = new ModelNodePart[materials.size];

int i = 0;
for(OrderedMap material : materials) {

I'm not sure which one (conv or loader) implementation is correct. Wither exporter or importer should be fixed.
"parts" looks more suitable.
