v2.2.2

• Weather: Alerts across Europe now match the ground they cover. Most MeteoAlarm feeds name a warning's region by code rather than by polygon, and linecast now ships the geometry for every one of those codes, so a warning for a county applies to the people in that county and to nobody else. The area-name matching that went wrong in Poland (issue #57) remains only for the few countries whose feeds carry neither polygons nor these codes.
