A module that will allow using ajax/jquery mechanisms for uploading multiple files to be attached to a single form submission. It will use an ajax/hidden-iframe method to upload each file individually (like Gmail does) to a temporary location, and then move the files to a permanent location once the form has been submitted. It will provide cleanup mechanisms, and the ability to handle multiple simultaneous requests to the same form. This module is not designed to be used on its own, but called (like the captcha module is) from within another module's php code.
