refs https://github.com/TryGhost/Team/issues/559 refs https://github.com/TryGhost/Team/issues/1277 - switched modal implementation to the newer promise-modal style - added `<GhEmailPreviewLink>` component that renders a link that when clicked opens the modal - removes the need for templates/controllers to manually handle modal opening/closing and to pass actions down from parents - updated all places we were triggering an email preview modal to use `<GhEmailPreviewLink>`
