[Nautilus-list] bonobo and xpdf from tag

[Darin Adler <darin eazel com>]

For now, Nautilus requires both bonobo and xpdf from the
BONOBO_BEFORE_API_RENAME tag, rather than HEAD. I've updating README to
reflect this. For those using eazel-hacking, this just means you should
"update" before your next rebuild.

The need for this comes because of API changes to Bonobo while we're still
working on PR2 using cvs HEAD. As soon as PR2 goes onto its own branch,
we'll move to the newer Bonobo. We're also considering following up the PR2
release with one that just updates to the newer Bonobo. Stay tuned for
details.
