How to control lazyload event on javacript to fix bug on Owlcarousel

- Customize the lazysize.js file by adding the code e.target.addEventListener('lazyloaded', function(e){});

- Remember to remove 'owl-carousel' default class of Owlcarousle plugin because it prevents Lazysize plugin to change the class name on the loaded elements.

- Finally, on main javascript code add another event handler for 'lazyloaded' event to an image element to handle stuff after image loaded.
