great, thanks.

We have to change the bounding box anyway, so the filename is not that
much extra effort once every 6 months to update. Anyway the Xapi/OSM data
download takes about 20 minutes to extract so for the test builds I've
stashed a cached copy on the download server but will re-enable the
fetching of the most up-to-date version for the final RCs. i.e. manual
intervention is required by the OSM install script maintainer anyway.
(which happens to be me right now)

What I'll do is keep the heavy lifting of the download in install_osm.sh,
but change install_gisdata.sh to make a symlink called feature_city.osm.bz2
to provide a steady filename for tutorials and e.g. any PostGIS data upload
to use.

honestly I can't promise that I'll be able to even quickly review any
scripts over the next couple of weeks; but I'll try to find the time
