[wsrp-wsia] [change request #239] Rewrite token

Document: Spec

Section: 10.2.1 +

Page/Line: 61/33

Requested by: Rich Thompson

Old text: wsrp-rewrite

New text: wsrp-rewriteURL

Reasoning: I just noticed that we introduced a portlet URL parameter called
wsrp-rewriteResource ... this conflicts with the desire to have the demarcating
token be relatively unique. This proposal eliminates this conflict while
increasing the uniqueness of the demarcations.
