devpi-server-0.8.4: using pip's link parser now

[holger krekel]

hi all,

devpi-server, the self-updatding pypi.python.org caching proxy,
just saw a new 0.8.4 release.  Instead of BeautifulSoup it now
uses pip's link parsing.  This should serve as a shortcut to avoid
real life crawling issues.  IOW, whatever pip can install, should
also be installable through the devpi-server cache.

More info, getting started, deployment info  on devpi-server:

thanks to Markus Zapke-Gruendemann for cleaning up some internals.

cheers,
holger
