Rip out setuptools

Too-specific requirements in other libraries are fucking with
setuptools' automatic path manipulation.

Traceback (most recent call last):
  File "/usr/bin/docker-sync", line 5, in <module>
    from pkg_resources import load_entry_point
  File "/usr/lib/python2.6/site-packages/pkg_resources.py", line 2659, in <module>

  File "/usr/lib/python2.6/site-packages/pkg_resources.py", line 546, in resolve
    raise DistributionNotFound(req)
pkg_resources.DistributionNotFound: websocket-client==0.11.0

Who fucking has time for this bullshit?
