Fix for Translating City names

The current Plugin as is dose not support translating the city names to multiple languages.
I made the following changes to fix that:
1- When preparing the cities:

function my_cities( $cities ) {
    $cities['XX'] = array(
        'YYY' => array(
            ['City in English'] => __('City in English','city_names'),
            ['Another City in English'] => __('Another City in English','city_names')
        ),
        'ZZZ' => array(
            ['City3 in English'] => __('City3 in English','city_names'),
            ['City4 in English'] => __('City4 in English','city_names')
        )
    );
    return $cities;
}

2- in the php:

foreach ( $this->dropdown_cities as $city_code => $city_name ) {
	$field .= '<option value="' . esc_attr( $city_code ) . '" '.selected( $value, $city_code, false ) . '>' . $city_name .'</option>';
}

1- in the java:
options = options + '<option value="' + index + '">' + cityName + '</option>';
