- Broke schema functions into separate object and got rid of DB_VERSION config constant in favor of a toVersion variable in the _migrateSchema command (which isn't technically necessary either, since the version number at the top of schema.sql is now always compared to the DB version at startup) but will help reduce the chance that someone will update the schema file without adding migration steps) - Removed Amazon scraper from schema.sql, as it will be loaded with the rest of the scrapers
