Subject: [PATCH] Specify explicit form element

This allows request elements external to the form to serialize a target form for use. An example might be a search form at the top of a page, list of results in the middle, then the pagination at the bottom. The pagination would need to target the search form with data-request-form to persist the search query value.

This should work with the JS API too, passed as an object, because $($()) is acceptable in jQuery
