* @version 4.2.6
*
* File input styled for Bootstrap 3.0 that utilizes HTML5 File Input's advanced
* features including the FileReader API.
*
* The plugin drastically enhances the HTML file input to preview multiple files on the client before
* upload. In addition it provides the ability to preview content of images, text, videos, audio, html,
* flash and other objects. It also offers the ability to upload and delete files using AJAX, and add
* files in batches (i.e. preview, append, or remove before upload).
*
