[Imports] Addition of building footprints in selected U.S. and Canadian cities

[William Morris]

Ian, Honestly - and with a certain amount of shame - I had planned to just
pull both sets of buildings into ArcMap and run location SQL (select from
UVM-SAL buildings where intersect with OSM buildings), then invert the
selection and export. It seemed like this approach is conservative toward
OSM feature preservation and might also be good for QA/QC in small batches.
Unfortunately I'm noticing that the cloudmade shapefile zips don't include
buildings. Moving on to the next idea . . .

Josh, I would happily assist on the plugin if I knew the first thing about
Java. I'm more inclined to lean on GDAL/OGR in the backend, but I agree it
would be fantastic to have this functionality in the editors.
