Code Issues Proposed changes

Add support to modal.js for file attachments in form response 

The non-modal forms handle this fine, but the ajax wrapping in modal.js
doesn't handle this properly and just appends the file data to the page.

This will correctly process the file, and download it before closing the
modal.
