Normalize extension names.

Remove a no-longer needed normaliation

Feature Changes
---------------

- Variable substitutions now reflect option data written by recipes.

- A part referenced by a part in a parts list is now added to the parts
  list before the referencing part.  This means that you can omit
  parts from the parts list if they are referenced by other parts.

- Added a develop function to the easy_install module to aid in
  creating develop eggs with custom build_ext options.

- The build and develop functions in the easy_install module now
  return the path of the egg or egg link created.

- Removed the limitation that parts named in the install command can
  only name configured parts.

- Removed support ConfigParser-style variable substitutions
  (e.g. %(foo)s). Only the string-template style of variable
  (e.g. ${section:option}) substitutions will be supported.
  Supporting both violates "there's only one way to do it".

- Deprecated the buildout-section extendedBy option.

----------

- We treat setuptools as a dependency of any distribution that
  (declares that it) uses namespace packages, whether it declares
  setuptools as a dependency or not.  This wasn't working for eggs
  intalled by virtue of being dependencies.

`67737 <https://launchpad.net/products/zc.buildout/+bug/67737>`_
     Verbose and quite output options caused errors when the 
     develop buildout option was used to create develop eggs.

`67871 <https://launchpad.net/products/zc.buildout/+bug/67871>`_
     Installation failed if the source was a (local) unzipped
     egg.

`67873 <https://launchpad.net/products/zc.buildout/+bug/67873>`_
     There was an error in producing an error message when part names
     passed to the install command weren't included in the
     configuration.

Don't upgrade if the buildout command is non-local.

  setuptools as one of its dependencies, we now treat setuptools as an 
  implicit dependency.  We generate a warning if the distribution
  is a develop egg.

- Remove old develop egg links. This requires storing the old link
  paths in .installed.cfg.

Non-zip-safe eggs were not unzipped when they were installed.

Updated release information.

versions.

Fixed a bug in installing by direct egg download.

the version of python used to run the tests is not Python-2.3.

Use pypi as the index when running these tests. This is,
unfortunately, necessary because when installing a source distro for
another version of Python, we need to download setuptools for the
desired version.  Maybe in the future we can figure out a way for the
tests to use a local copy of setuptools.
