HaikuDepot: Limit language selection for account creation

For the time being, there is a limited amount of supported languages
when creating accounts, reflect this in the UI and use a BMenuField.
Creating accounts with other languages fails, the error reporting was
not ideal and could be improved. The server responded with "object not found",
which was reported in the alert, but the response actually contains the
object which was not found (NaturalLanguageCode).
