Subject: [PATCH] fix handling of country-less languages like esperanto

it's impossible to instantiate QLocale objects like that, so the
language setting would be simply clobbered. instead, we now convert
between numerical and string codes directly.

unfortunately QLocale has no public api for that. but we are including
private QTranslator headers already anyway, so whatever.

Task-number: QTBUG-14592
