docs: Support helper options defined on `app.options.helper`. For example,
  to define options for helper `foo`:
  
  ```js
  app.option('helper.foo', {doStuff: true});
  ```
  @param {Object} `app`
  @param {Object} `helpers` Currently defined helpers, to match up options
  @return {Object} Returns helper options
