Subject: add the replace kind of remake

POST /admin/remakes accepts specs with replace kind, e.g.:

  { "kind": "replace",
    "baseHeads": ["..."],
    "spec": {
      "document": { "accounts": { ... } },
      "rules": [
        { "from": "users",       "to": "accounts" },
        { "from": "users/admin", "drop": true },
        { "from": "",            "to": "" }
      ] } }
