To reduce the memory footprint, this patch no longer loads the JSON data completely into memory. Instead, there is an SQL database based on `ExpireCacheSQLite`. The class CurrenciesDB is a simple DB application that encapsulates the DB (queries and initialization) and provides convenient methods like `name_to_iso4217` and `iso4217_to_name`.
