Remove alternative language for map language

Remove alternative language for map language

Good point. alt_name, old_name, int_name, default "languages" should be removed.

Please check coding/string_utf8_multilang.cpp and filter out not needed items from the language list.

Map languages list is initialisated exactly from this file...
Or you mean, that some languages from this file can't be chosen for the map? In this case: by what attribute can this be understood?

I've listed the language names that are not languages, but artificial OSM-defined tags. They should be removed.
