/**
 * The Shadowbox ajax player class. jQuery ONLY!
 *
 * Retrieves and displays partial HTML from server via Ajax
 * (where 'partial' implies valid HTML, but not a full web page!)
 *
 * To use:
 *   Set player to 'ajax'
 *     eg. < a href='ajaxpartial.php' rel='shadowbox;player=ajax'>Link< /a>
 *   By default, the expected response format is HTML
 *
 * The ajax() call options can be overriden by setting Shadowbox options.ajax
 * to an object containing Options and defined on http://docs.jquery.com/Ajax/jQuery.ajax#options
 * eg. to set a JSON data type (instead of HTML)
 *   var opts = { ajax : { dataType:'json', success:myAjaxHandler }
 *              , player: 'ajax'
 *              };
 *   var myAjaxHandler = function(data, responseText){
 *       this.html = '<div>'+data.text+'</div>';
 *       this.ready = true;
 *     };
 *   Shadowbox.init(opts);
 * Be warned : there are numerous options available for the jQuery.ajax() method, and
 *             experimenting with them can easily cause the call to fail!
 * NOTE : If overridden, the success, error and complete callbacks get context of the Shadowbox.ajax
 *        instance, in place of the XMLHtmlRequest that is usually the context for jQuery.
 *        The callbacks - especially success - are expected/required to set this.html to
 *        hold the displayable HTML, and this.ready = true to indicate that the ajax call
 *        is complete and ready to be shown.
