Link to cart option

Hi, thank you for the amazing plugin. I really like it.

It would be great to have the option of linking to checkout OR cart.
Now it’s only straight to checkout.

Thing is: some webshops have cart-options (minimum orders in our case), that is being skipped now.

In our case: we had to adjust the plugin in the file loop-end.php; the replace the checkout_url function to the cart_url function.
