[x3d-public] X3D4 endgame review: normative references and informative bibliography

[Don Brutzman]

We've updated a number of reference and bibliographic entries.

Request review and comment.  A number of these references remain valid but are somewhat dated, and we have added several new technologies... so if additional or different entries seem appropriate, then please suggest them.

[1] X3D4 Architecture, Normative references
     https://www.web3d.org/specifications/X3Dv4Draft/ISO-IEC19775-1v4-WD3/Part01/references.html

[2] X3D4 Architecture, (Informative) bibliography
     https://www.web3d.org/specifications/X3Dv4Draft/ISO-IEC19775-1v4-WD3/Part01/bibliography.html

Have fun with X3D4!  8)

all the best, Don
