Added posibility to pass custom animation for new translation.

Now we can do:

        $('.lang-translation').translationFields(
            {
                addAnimation: function(){
                    return this.css({backgroundColor:"#FFF", position: "relative", top: -25})
                               .animate({backgroundColor: "#2be", top: 0}, 500).animate({backgroundColor: "#eee"},200);
                }
            }
        );
Update of animation and added mark translated options.

Now in the select each option that is selected will have a translated class.
