install scripts using setuptools

- lookup.py was deprecated in favor of setuptools entry_points; the code for
  lookup.py was moved to django_sshkey.util.lookup_main
- lookup.sh was renamed to django-sshkey-lookup since setuptools retains the
  names of scripts once installed. A symlink has been left in place.
