Multiple Job submission forms

Requested in 5188773-zen

**Usecase**

The first job_submit shortcode lets the customer submit a job posting.

The second job submits a shortcode that lets the customer submit a Classified like a car or a book.

So the first form would have all the fields regarding jobs, like job title, and job description.

The second form would have all the fields regarding the classified like title, description, pick up / shipping possible, mint condition/used, etc.

Start by locating the job_submit shortcode and tracing how its submission form is built. Compare the existing job fields with the requested classified fields; done should mean the shortcode supports separate forms for job postings and classifieds, with the appropriate fields for each.
