First stab at using setuptools >= 0.7 instead of distribute.

My doctest / renormalizer fu is not strong enough to deal with the
changes to output:

- setuptools now has dependencies, and emits output to add them as
  'find-links'.  I tried adding an 'adding_find_link' renormalizer,
  but it doesn't suppress the output.

- Other failures due to merge tweaking APIs, etc.  Again, I'm not
  competent to fix them in the doctest / renormalizer world:  they make
  my head hurt.
Fix URL normalizing out the 'Adding find links...' output from setuptools 0.7.

Use that normalizer everywhere.
Update to new (provisional?) ez_setup.py URL.
s/distriBUTE/setuptools/
Fix sorting.
Don't repeat a dist in the signature.

Even if distutils / setuptools gives it to us more than once.
Drop the 'no_fake' argument when calling ez_setup.

We don't need to juke faking setuptools (or not) when we are using
setuptools rather than distribute.
Note switch from distribute 0.6.x to setuptools 0.7.x.

Bump version to indicate change in dependencies.
