Added a pip config file to support virtualenvs created with option --system-site-packages. The recommended way of creating a virtualenv for the datatracker is now '$ virtualenv --system-site-packages env', placing the virtualenv libs and binaries under env/bin/ and env/lib/. Also updated the ietf/wsgi.py file to use this.
