new devpi-2.0.1/2 releases: fixes, new anonymous upload

[holger krekel]

The new devpi releases (devpi-server-2.0.2, devpi-web-2.0.1, devpi-client-2.0.1)
contain several fixes for the private github-style pypi caching server, 
see the changelog below for details.  Find all the documentation at

    http://doc.devpi.net/latest

with tutorials and quickstart documents for particular scenarios.

Note that no export/import procedure is needed if you are already running
a 2.X devpi-server.  If upgrading from a 1.2 devpi-server install, you need
to upgrade using these instructions:

many thanks to Florian Schulze who again helped a lot with this release.

have fun,
