3d_mods: pass: led: abbreviate orange to ORG
mods: pass: update orange to ORG linked model filename
3d_mods: passive: Updated X3D model colorization

These models were some of those that are not rendering properly in
KiCad, so experimenting with them based on the following:
  - Changed ambient and specular in Wings3D to 0.15, 0.15, 0.15.
  - Exported to OBJ, imported to Blender, and exported to X3D.
