Small change to allow caller to pass on a callback function and its arguments that would be called whenever retreival of feed is done:

From caller's perspective :

    function callback(args){
       [...]
    }

    $("#myid").FeedEk({
    FeedUrl       : url      ,
    MaxCount      : 20       ,
    ShowDesc      : false    ,
    ShowPubDate   : false    ,
    [...]
    Callback      : callback ,
    Callback_args : {...}    ,
    });

Changes made to Feedk.js' success property :

            success: function (data) {
            ...
                if (def.Callback) {
                    def.Callback(def.Callback_args);
                }
            }
        });
    };
    })(jQuery);
