s/URI References/URIs/ in VocabManagementNote

re "2.1. Identify Terms with URI References."
  -- http://esw.w3.org/topic/VocabManagementNote

The right term there URI. We identify with URIs.

URI references are things used in data formats to abbreviate (or spell 
out in full) URIs.

The historical problem where the term "URI" didn't include things with 
#fragments
is now fixed in

    URI
      IETF STD 66, RFC 3986: Uniform Resource Identifier (URI):
      Generic Syntax, T. Berners-Lee, R. Fielding, L. Masinter,
      January 2005. Available at <http://www.ietf.org/rfc/rfc3986.txt>.

see http://www.w3.org/TR/webarch/#uri-refs

I suppose I could have made this change myself, but I gather that's not
the preferred process. Let me know if I gather wrong.
