Issue CertFusion certificates for new systeme.io webinar registrations

Training webinars run through systeme.io frequently carry CPD, CEU, or CME credit, which means every participant needs a certificate—and systeme.io leaves you to make them yourself. This Zap picks up each new webinar registration, adds the registrant as a CertFusion recipient, and issues their certificate from the design you've set up. Their name and email transfer directly from the registration. Your credit certificates go out automatically, however many people sign up.
