[fixed] Couldn't reproduce at importing completely an .obj file that has vertex color

[tkbd]

Hi!
Wings3D couldn't reproduce at importing completely an "obj" file that has vertex color.

I wanted to handle colored voxel surfaces on Wings3D and goxel.
goxel is nice 3D voxel editor for modeling,coloring and rendering.

It also can export an obj file with vertex color info.
So I import the obj file by Wings3D, but the Geometry object has no vertex color.

For example of obj data(this case has vertex color)
#v x y z R G B
v -9 11 1 1.000000 0.000000 1.000000

Each R/G/B value range has (No color) 0.0 - 1.0 (Colored)

See a screenshot

And I attached a sample file the obj data.
vtex_color_obj.txt (Rename to vtex_color.obj)

Best Regard
