Saving attributions to metadata

[elliotBraem]

If a widget looks like this on the social contract:

{
  [accountId]: {
    widget: {
     [widgetName]: {
        "": JSON.stringify(code),
        "metadata": {
          name: "",
          description: "",
        }
      } 
  }
  }
}

We could extend metadata to include an array of users to attribute. This could be handled from bos-workspace, with an ultimately goal of it potentially populated based on mappings of a user's github handle with their near account.
