Feature: Additional fields partial in new job form 

Description 

The form template Templates/Job/New.html of the New job form renders a new partial, Partials/Job/Forms/AdditionalFields.html, between the job properties and the submit button. The partial the extension ships renders nothing.

A site adds a field to the form, a captcha for example, by overriding that one partial. Until now it had to copy the form template or the partial of the job properties to do so. A field in the partial is named outside the job argument of the form, because a field bound to a property the job model does not have makes the submission fail. See Add a field to the new job form.

Impact 

The form renders as before. A site package that copied Templates/Job/New.html does not render the new partial until it adopts it in its copy, or drops the copy when it only existed to add a field.
