[x3d-public] glTF asset metadata support

[Don Brutzman]

Great metadata discussion on the weekly Design Printing Scanning teleconference.

We decided to specifically call out that any metadata in a glTF asset (model) needs to get loaded as X3D metadata.

Feedback and improvements welcome.

================================================

Mantis issue 1272: glTF import needs to include metadata import
https://www.web3d.org/member-only/mantis/view.php?id=1272

When loading a glTF model, whatever metadata might be embedded needs to appropriately converted into X3D head/meta elements or Metadata* nodes as well.
