This CL introduces currency declaration support in adapters bid respo…

…nses as described in prebid#280. (prebid#491) This change covers: * Introducing a new struct `BidderResponse` carrying the list of bids `TypedBid` and a currency as string * Change the existing adapters using the new API `MakeBids` so it start using the new `BidderResponse` struct This change doesn't cover: * Doesn't change the former API using `Call` method * Any check done on Pre-bid server side to discard any bid received with an invalid currency (such as unknown, or a one that wasn't authorized in a first place via trhe bid request) * Any mechanisms on tranlating currency rates As a nice next step, we should implement the mechanism to filter bids having invalid currencies on not allowed ones. It will allow to protect both parties from currencies mismatch / discrepancies.
