Title: add onVisible callback

add onVisible callback
callback will be called when the element in viewport

it's useful to extend functionally outside.
like this example in my project, I can do anything i want on 'elem'
```
window['lazyshow'] = lazyload({onVisible: function(elem){
$(elem).addClass('fadeIn');
}})```
