Avoid using cached request

[8geonirt]

Fixes #158

• There's a common issue when hitting the cart.js endpoint from Shopify, it's cached by default so it's causing an issue when loading items from the cart, sometimes the cart shows up as empty when hitting the back button.

This commit adds a timestamp to the API call to get a non-cached response. This approach is done by Shopify itself to avoid loading cached assets

Note: I am maintaining a Shopify theme and we have a custom slide cart component created from scratch (no libraries used), we faced the same issue and before creating a fix for this I found this library and I would like to contribute to it with that simple fix.

It seems this isn't working anymore and the cart.js endpoint is being cached regardless.

Another workaround:

$.ajax({ type: 'GET', url: '/cart.js', cache: false, dataType: 'json', success: function(cart) { CartJS.init(cart, { "moneyFormat": "{{ shop.money_format }}", "moneyWithCurrencyFormat": "{{ shop.money_with_currency_format }}", "requestBodyClass": "cart-loading" }); } });

Thanks @capatina. I have an underlying change to pass cache: false in the Ajax request, should be released shortly.
