Title: Add a --setuptools option

This adds an explicit --setuptools option, and an implicit $VIRTUALENV_SETUPTOOLS environment variable. It also explicitly sets the default value of `use_distribute` to False for backward compatibility. However, this will allow us in Debian to easily change the default to use distribute (as per Debian policy).
