Plone-formwidget-multifile

------------------

* Changed the UI so now there's a link to "add files" instead of an standard
input[type=file] HTML element (which still exists, but is hidden). Users were
complaining that the old UI was confusing since the textbox of the
input[type=file] element was always empty.

------------------

* Removed integration with jQuery plugin. Instead we use HTML and javascript,
and when applicable, the "multiple" extension from HTML5 which lets a
user upload multiple files at once.
