forcePartial option

Add option to avoid wiselinks interpreting the response as a Full Document Response when having only one target.

When enabled the following headers will be always used (even if the target is 1 element):
* X-Wiselinks-Assets-Digest
* X-Wiselinks-Title
* X-Wiselinks-Description
* X-Wiselinks-Canonical
* X-Wiselinks-Robots
* X-Wiselinks-LinkRelPrev
* X-Wiselinks-LinkRelNext
