Title: Add option to use virtualenv with --system-site-packages

Currently, it is not possible to build docs for a project which needs to install dependencies that depend on numpy+scipy. Even though numpy and scipy are installed on the build servers, it is not accessible from the virtualenv as the virtualenv uses --no-site-packages. Installing numpy and scipy within the virtualenv also does not work, as scipy's setup.py already needs an existing numpy installation. This commit adds an option allowing to use virtualenv with the "--system-site-packages" option, closing issue #218.
