This contribution allows a second currency to be displayed while still sending the default currency at checkout. This is important since some payment modules require payment in US funds. To accomplish that, the currency in the shop must be set to US prior to confirming the order, which makes it difficult for customers from different countries to realize what they are actually paying. With this contribution, both currencies can be displayed at various places in
the shop, depending upon an admin setting, so that the customer always knows what he is paying.
