This is still marked as a draft. What work remains?

[peterbecich]

@gbaz , I need to manually test these work as before:
candidate-index, candidate-page, the Hackage dependencies graph, package-page, and tag editing

If we are willing to risk the features being broken it can merge now

[gbaz]

there's no urgency, this is a maintenance change. might as well let it take the time it needs.

• candidates: I'm having some trouble updating a candidate to local Hackage instance. "Forbidden". http://127.0.0.1:8080/packages/candidates/ How do I give the admin user this permission? Is there a group, such as http://localhost:8080/packages/mirrorers/?
• dependencies graph
  • https://hackage.haskell.org/packages/graph works
  • http://localhost:8080/packages/graph broken on this PR; something must be broken in the JavaScript
  • it works locally on master:
    
• package-page looks fine http://127.0.0.1:8080/package/Blammo
  
• tag editing looks fine
