allow top level descriptions for settings

[mandric]

It would be useful to explain/describe a new setting/group by rendering a description field value. I don't think this deviates from json.edit spec but I should double check.

"kujua-reporting": {
           "title": "Scheduled Reports",
           "type": "array",
           "description": "The forms to include in reporting rates stats.",
           "items": { ... }
}

Trying this after merge from master branch and still not seeing a top level help. Before the form elements get rendered we should see "The forms to include in reporting rates stats.".

Oh let me also include the json.edit changes #45 and try again.
