Add verification workflow
This would add a concept of 'verification' to Certifications.
Users can create their own Certification in an unverified state and then be verified by someone else. It would want a way for users to see their certifications pending verification and a verifier's dashboard to see pending verification requests and approve them. Maybe needs some dates for when certification was created and verified. What happens to any that are not verified?
An evidence upload field (#11) would be useful here.
