[X3D-Ecosystem] Initial work on PhysicalMaterial support in Blender

[John Carlson]

Looks great, Vince.  I've been meaning to post about HAnim export process.

1.  Animation isn't working well yet, or isn't organized.  I haven't
checked skin weight info lately

2.  I have 2 separate forms of geometry, one under joints, and one under
transforms.

3.  I ran through Michalis' examples, but the 2 HAnim examples I'm working
on are Vince's sand runner and Katy's Gramps.

4.  Contributions of Jin*'s or Joe*'s or Korean* in blender format are
welcome!

5.  Michalis's quick HAnim works, last I checked.  I'll go back to that as
a based case.
