added switching between search engines

- works with different languages - works with links refactored selector code: - changed method names - changed method parameters (object -> id), - added method to rename all options of dropdown menu refactored distance format selector code: - changed method names - changed variable names - changed how to init/select element/change language of dropdown menu refactored maintenance notification overrides: - changed names of default variables
