Vadim Zeitlin 17041075b4 Fix wxLanguageInfo::GetLocaleName() 
This function could (and did) return completely wrong results because
the value of the pointer returned by setlocale() could be (and was)
changed by the subsequent call to setlocale() with different arguments.

Fix the problem by copying the returned value into wxString immediately,
without any intervening setlocale() calls.
