Implements functions to use mouseover/out

Implements functions to use jquery's mouseover/mouseout.
Now you can use like this:

$('#wrapper').scrollbox({
    linear: true,
    delay: 0,
    speed: 60,
    autoplay: false,
    onMouseOverPause: false
});
 
$('#forward-arrow').mouseover(function () {
    $('#wrapper').trigger('forwardHover');
}).mouseout(function(){
    $('#wrapper').trigger('pauseHover');
});

Thanks.
