Update a Persona

Updates a Persona. Send the base_revision you read. Omit a section or an age bound to keep it. Send null to clear it. AdCrunch checks the age range on the result of the merge. Therefore a call that sends only age_min can still fail, if the result is inverted. The slug changes only when you send a slug: a new name alone never moves the handle. The answer is 409 with error=revision_mismatch if the Persona changed after you read it. It is 409 with error=slug_conflict if another Persona of this Brand already holds the slug you send.
