[Rivet] FastJet "robot" downloads blocked

[Andy Buckley]

Hi Gregory, Gavin, et al,

We've noticed recently that the FastJet website blocks "robot" downloads
of the FastJet tarball, e.g. http://fastjet.fr/repo/fastjet-3.0.3.tar.gz

Unfortunately this means that the Rivet bootstrap script can fail if it
tries to download and build FastJet, rather than using the LCG installed
copy from AFS. We're using Python's urllib2 to do the fetching... is
there anything weor you can do to not fall foul of this blocking? (I'm
not sure if urllib2 automatically respects robots.txt files, but if you
want to give us a special unblocked User-Agent name to use, I'm sure we
can manage to update our script accordingly)

Thanks!
Andy & co
