City names are now disambiguated by a two-letter country code. This
commit handles almost everything needed to make this transition. Main
next steps are fixing up map edits automatically and making the city
picker UI understand the extra level of hierarchy.
A little bit of fallout: lakeslice gridlocks again; this regression is
actually from the recent traffic signal changes, but I'm just now
regenerating everything. Will fix soon.
use the site name as the city, instead of picking the "closest" major
city. This is introducing too much friction in automation.

There will be a few awkward results -- cambridge gets renamed, and lcid
gets disassociated from leeds. Worth it for now.
