OBJParser - assign wrong material (shifted by one group)

What steps will reproduce the problem?
1. Try to load OBJ file and MTL with multiple groups.

What is the expected output? What do you see instead?
Materials are assigned to groups but shifted by one. 

What version of the product are you using? On what operating system?
away3D 4.0 [bromstick]

Please provide any additional information below.
When parser read 'usemtl', create new material ID and set it as active 
material, but doesn't set it to _currentGroup.

OBJParser, add this line, under line 194:
if (_currentGroup) _currentGroup.materialID = _activeMaterialID;
