v0.2.1

Fixed

• The documentation names the right packages. The site description said the
  command runs a django-spec-cli registry, where the registry is
  django-service-specs'; the SpecCommand docstring and the index page compared
  pool_seeds to SpecView's as if the kernel still shipped it, where it now
  lives in django-spec-html; and the README's LICENSE links were relative, which
  break on PyPI. No code changes.
