[Buildingdata] Ex-buildings

[Christopher Gutteridge]

I've just seen a portacabin building dismantled; 
http://data.southampton.ac.uk/building/86.html is gone!!

I'm wondering if it makes sense to have a class for ex-buildings, so 
that if something refers to it, it's explicitly a demolished building 
(well, carried away on trucks in our case) rather than just a 404.
