        Preliminary: we download and enable ant-contrib tasks, unless a
        timestamp file exists that tells us this is already done.

        As an alternative, we get ant-contrib from the system itself if the
        antcontrib.system.location is set in antcontrib.properties.

        As we don't have ant-contrib yet at this stage (obviously), we must
        rely on a proxy task to tell whether the timestamp file exists.
