OBJ Import

* Wasn't setting the curve 3D option
* The nurbs object name could be None which caused an error, check its set.

OBJ Export
* Off by 1 error on closed nurbs was incorrect, broke other importers but worked with blender.
* Nurbs verts were not adding to the total vert count, scrambling meshes added after (somehow my first test case had all the curve objects last)
