Locale cleanup from the locale atlas

- Remove keys nothing references any more (meeting_murakami/growl,
  opt_home, opt_alley) in en/ru.
- An empty select "" carries no key=: drop meeting_murakami/after_wolf/
  choose_enter from the scenario and from scenarios_en.
- locale/scenarios_ru.properties: Russian scenario strings get their own
  file next to scenarios_en.

locale/scenarios_en.properties
