workaround for incompatibilities with gunicorn >= 0.17.0
see esp. https://github.com/benoitc/gunicorn/commit/b7b51adf13e92044211b267ba07e3498585f219a
add an ugly redundant compatibility hack to support gunicorn < 0.17.0
Added support for the `log_file` attribute when creating the server.  Allows
you to redirect the access log to a file (or /dev/null) instead of `stderr`
as pywsgi does it by default.

This also works in the .ini through the "paster" integration thing.
