@plone/types: Batching information missing from batched requests

[JeffersonBledsoe]

A request to http://localhost:8080/Plone/++api++/@querystring-search include the following object:

batching: {
    '@id': 'http://localhost:8080/Plone/++api++/@querystring-search',
    first: 'http://localhost:8080/Plone/++api++/@querystring-search?b_start=0',
    last: 'http://localhost:8080/Plone/++api++/@querystring-search?b_start=9',
    next: 'http://localhost:8080/Plone/++api++/@querystring-search?b_start=3'
  },

This information is missing from the types. It's probably used elsewhere as well, I just haven't tried anywhere else yet...
