Added an option to supply entry points directly. This is useful for
packages that don't declare their entry points.

No longer generate "py-" scripts implicitly.  Added a new option,
interpreter, to request such scripts and specifu their names.

Increased default buildout logging.

invoking easy install.  This should make things go faster in practice.

Stop giving setuptools special treatment when downloading.
Unfortunately, this means tests take a lot longer to run and probably
that they can only be run when connected. :(
Maybe I should figure out a way to get stuptools to use a different
default index when running tests. :/

It would have broken old bootstrap scripts.  Now my problem is that if
I update buildout in a way that recipes depend on, people will have to
update their buildouts by running the bootstrap script. This isn't ideal.

generated script paths.

Added an arguments option to specify source for arguments to be passed
to entry points.

generated script paths.

The sample buildout is now created using the bootstrapping mechanism
and so has a normal layout.

No longer read ~/.buildout/.default.cfg, when running tests.
(We do read a ~/.buildout/.default.cfg when testing that function, but
we manipulate HOME so that we control what is read.)

The characters "-", "." and " ", weren't allowed in section or
option names.

Substitutions with invalid names were ignored, which caused
missleading failures downstream.

- Now require a recipe option (and therefore a section) for every part.

brittle and failed tests with the latest setuptools.

trailing newline.

  warning that it is being created.

- Fixed bug in saving installed configuration data.  %'s and extra
  spaces weren't quoted.

Fixed a bunch of typos in tests
