Fix for WooCommerce 3.0.4

I have tested and can confirm this plugin works with WooCommerce v3.0.4. It does need one modification to assets/js/public.js

Replace the following lines

Line 27 $("#select2-shipping_state-container").html(stateName).parent().removeClass('select2-default');

Line 51 $("#select2-shipping_state-container").html(stateName).parent().removeClass('select2-default');

This will fix the state fields when changing between saved addresses.
