Title: Bug/combine shapes

As in reply to Gostwalker71's bug issue he had with blender CTD
everytime he toggled edit mode, I have found the bug and probably the
reason for the render issues with collision objects.

Ghostwalker71's Bug:
1) Import Nif
2) Click Combine Shapes
3) Import Apple01.nif
4) Toggle Edit Mode
5) Blender Crashes To Desktop (CTD)

My Findings:
After reviewing the relative code, and through extensive testing and
trial and error, I have eliminated the above bug and successfully
completed steps 1 to 4 without Blender CTD.

As per my commit, I have modified the face generation for group meshes.
And I also removed(commented) 'b_mesh.update()'. This bug seems to
be caused by bpy.data.objects[].data.update().
