Always trigger global listeners - add Shopify.onItemAdded & Shopify.onCa...

Hey ...

It's important to have these general listeners trigger to be able to easily customize the AJAX cart. The settings.onToggleCallback is not enough as it's called before the AJAX completes and can't be used to manipulate the cart. Currently to resolve this we have defined global AJAX listeners which check the request's URL to determine which action is happening (cart.js, add.js etc...)

With these cart listeners it will be much easier to add a loader, apply currency formatting or any other cart customization required.

I also added a default Shopify.onItemAdded and a new method Shopify.onCartOpen which is called after the AJAX request to open the cart completes.

Thanks :)

It got all mixed up when I merged latest master with the fork ... Let me know if you're interested in this change and I'll make a new pull :)

I have an issue open for the callback firing before it should.

It'll fix the issue you're seeing, and avoid any confusion trying to custom set callbacks. Shopify.getCart for example, doesn't always mean the cart is open so calling Shopify.onCartOpen doesn't necessarily make sense. Keep an eye on the issue above and we should get to a solid solution.
