Oops, will fix that on the next pass... :/

I'd actually like to defer these - the finishing intent attributes (finishings-supported, finishings-col-database/ready, etc.) already expose most of this information in a way that can be used by the Client.  The only information we didn't have a way to get via IPP was the capacity of the finisher subunits - how many sheets can be stapled, etc.

Longer term (probably in System Control) we can expose things like deviceModel for use by management applications.  But anything regarding capabilities should already be exposed by the new finishings-col stuff (and if not then we should add it there and not using the octetString key/value syntax).
