Create main bar page widget, allow quicker buying
Currently, the quick buy list for users on the bar page requires a new page load to buy a product.
Create a widget with an AJAX call for buying. Allow the user to quickly tap to buy multiple products. The client should assign an unique ID to each buy and keep it in local storage. Buy calls should be attempted again on next load if they didn't complete yet. The unique ID can be used to determine whether a product was bought already. Show a loading indicator while a buy is processing, and block page reload during this.
