[x3d-public] x3d resources basic web3doutreach example. Spaces in filename, ExternProtoDeclare URI not allowed.

[John Carlson]

http://www.web3d.org/x3d/content/examples/X3dExampleArchivesJsonScenes.zip has not been updated, AFAICT, FYI.

$ jar -tf ~/Downloads/X3dExampleArchivesJsonScenes.zip|grep Cube.logo
www.web3d.org/x3d/content/examples/Basic/Web3dOutreach/Cube logo prototype.json

$ jar -tf ~/Downloads/X3dExampleArchivesJsonScenes.zip|grep -i cubelogo

Will have to convert myself and svn update.

The issue is that a space character appears in the url value.  That is a good diagnostic of a bad practice.

Avoiding such spaces is listed in

	X3D Scene Authoring Hints
	http://www.web3d.org/x3d/content/examples/X3dSceneAuthoringHints.html#NamingConventions

The fix was to properly rename, checkin and cleanup multiple models for the Virtual Reality Hackathon (VRH) logo.

This is great content that is now a bit more consistent and reusable.
