Make it easier for inquisition subclasses to specify custom response classes.

We are using this same pattern in the AdminObjectEdit - nothing is to prevent subclasses from overriding the `getResolvedResponseWrapperClass()` if they don't want the class mapping.

The use of `resolved` is supposed to point to the auto-magicness of it all, but your point is good - it could lead to mistakes down the road with class mapping if we're not careful.

I still think it's okay, but open to further debate on the pattern.
