Multipart forms

Multipart form support is provided on 2 levels:

  1. Through the creation of a MultipartFormBody which can be set on a Request.
  2. Using the Lens system, which adds the facility to define form fields in a typesafe way, and to validate form contents (in either a strict (400) or "feedback" mode).
