A request with header and entity

[artemkorsakov]

Could you tell me please how can I create a request with a header and an entity like:

Request.get(Path / "user" / Param.int)
  .extractHeader[`Cookie`]
  .withEntity(Entity.formOf[CreateUserType]),

and get handler like:

Routes.addUserType.handleIO {
  (cookie: `Cookie`, newUserType: CreateUserType) => 
     ???
}

The entity part should work, but at the moment there is no way to programmatically set headers, which is a major oversight.

Two tasks to fix this:

• Document entity handling in responses
• Add the ability to programmatically set headers, and document it
