[Rd] Link to R 2.12.0 patched build for windows

[Brian Diggs]

On the download page for windows builds of R 2.12.0:

http://cran.r-project.org/bin/windows/base/

The link for "r-patched snapshot build" goes to:

http://cran.r-project.org/bin/windows/base/rpatched.html

which has a link for R-2.11.1 patched.  I believe that link should go to:

http://cran.r-project.org/bin/windows/base/rtest.html

which does have a link for R-2.12.0 patched. Or the "rpatched.html" page 
should be updated with a link to R-2.12.0 patched.
