generated settings.yml should use string hash keys
generated settings.yml should use string hash keys

When writing to config/settings.yml ONLY use strings for hash keys -- do not use symbols.
On app startup config/initializers/load_config.rb reads in the settings and creates
the APP_CONFIG hash with symbolized keys ... so read access in the app uses symbols.
