Title: Make stripe works with  canadian based shop.

That fix creates a new preference `currency` which allows to specify the currency in which the transaction should take place.
Default is set to 'USD'. If you want to use Canadian dollar, CAD should be used
This was tested using the test API from stripe for a canadian based shop
