Update wholesale price based on supplier price and currency

To be frank, the unit price and currency isn't being used in PS at the moment. It'd be a great thing to be able to update the wholesale price of all articles based on those fields. If there's more than one currency, then perhaps offer a choice box or do a median of all available?

Of course, the wholesale price would need to be set to the shop default and thus need some conversion, but if 1€=10SEK for instance, that's not a hard calculation, Ref-currency times value, basically.

This would help to find products that are falling below profitable ranges.
