export_cal3d - exporting all actions (option) wasnt working

export_fbx - blender cameras now work properly (converted lens angle, rotate to the right axis) Made meshes, armatures and cameras use the same namespace. DirectX8Exporter - update from David Teviotdale, change names of exported objects so some DX readers dont fail xsi_export - Null materials made the export fail (python error). This may not be a correct solution since material indicies could be messed up now. I have no way of reading these files.
