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
