Use delegated event handler to delete tax rows

When a tax row is dynamically inserted, it can not be dynamically
deleted until the page is refreshed (becasue the event handler is
bound to only on page load). This commit delegates the event handler
from an element which is guaranteed to exist on page load, so that
dynamically inserted tax rows can also be dynamically deleted.

@coenjacobs See this. Custom ajax handler and cart refresh per page load to get around cache issues. Custom handler foes *feel* a little wrong but since it doesn't load admin, it loads 100% faster.
