Locale cleanup from the locale atlas

- An empty select "" carries no key=: the prompt keys go from the
  scenarios and from the locale files.
- Scenario option strings live only in scenarios_<lang>.properties; the
  duplicates in en/ru.properties are removed.
- English names/info for the map zones (mapzone/home, town_entry).
- locale/scenarios_ru.properties: Russian scenario strings get their own
  file next to scenarios_en.
