Reforming of the Uploading

You can now upload in the jobs creation screen, and also delete uploads from there.

As part of this, there is no more jobs/new route.  A POST to jobs always makes a new job, then goes to jobs/edit straight away.  That way there is a job object for you to upload against right away.

Known Issues:
* The Download guy can't see anything to download!
* There is no 'delete' button or thumbnails for uploads in jobs/show
* There are no thumbnails in the jobs/edit for the files already uploaded.
