Remove 'distribute' dependency

This dependency is unnecessary since this project now uses setuptools and
it prevents installing this package with --use-wheel, failing with this
traceback:

$ pip install --use-wheel distribute
Downloading/unpacking distribute
  Downloading distribute-0.7.3-cp26-none-linux_x86_64.whl
Requirement already satisfied (use --upgrade to upgrade): setuptools>=0.7 in ./venv/lib/python2.6/site-packages (from distribute)
