    content: add a link back from "thank you" to "downloads" page.
    
    We know that people can just hit the Back button, but such an explicit
    text that the download was supposed to start is kind of common. And it's
    nicer to tell people that the download was definitely expected to have
    started. If it didn't, something is wrong.
