[Catalog-sig] Stable-releases-only PyPi

[Sergey Schetinin]

So I did what Phillip suggested. Also I now don't filter out the
less-stable releases completely -- I remove the links, but still list
them, so it's easier to see what the proxy does. For example:

http://pypi-stable.maluke.com/simple/setuptools/
http://pypi-stable.maluke.com/simple/lxml
http://pypi-stable.maluke.com/simple/WebOb
