devpi-server-2.0.4 hotfix for pypi.python.org change

[holger krekel]

devpi-server-2.0.4 is a hotfix release to adapt to a pypi.python.org change 
from three days ago which would cause devpi to fail installations 
for packages like "Sphinx", "Django" ... because pypi now serves
them under their canonical name instead of the registered one.

As usual, docs for the devpi system are at http://doc.devpi.net

best and have fun,

devpi-server 2.0.4
--------------------

- fix issue139: adapt to a recent change in pypi which now serves under
  URLs using normalized project names instead of the "real" registered
  name Thanks Timothy Allen and others for sorting this out.

- fix issue129: fix __init__ provided version and add a test that it
  always matches the one which pkg_resources sees (which gets 
  it effectively from setup.py)
