 * @version 4.2.7
 *
 * 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).
