Addition of an unspecified for third-party-collection

[doamatto]

What do you want added to PrivacySpy?
If a privacy policy is unclear or vague, policies may not be graded properly. With a vague third-party-collection, the default would be no (100%), which would be wrong if said third-party-collection was along the lines of "If we collect other data that isn't here, we'll use it within this policy.", with it being expanded to third-party processors as well.
