    enum template: Add more titles to navigation bar
    
    The current enum template only mentions the "Description" title (and
    "Functions" if applicable). However, depending on how long the
    description might be, it's a good idea to also add a link for quick
    access to the members. There's also an error domain below that, so let's
    link that as well.
