New location for 2.1 Requirements document

[Lofton Henderson <lofton@rockynet.com>]

FYI...

http://docs.oasis-open.org/webcgm/v2.1/WebCGM_21_Requirements.html

The bad links are fixed, and this is now a location with a permanent URL 
that you can put into "References" (or bookmark, or whatever), without the 
risk getting some obsolete Kavi artifact.
