Fix algorithm for finding localized files

Browse Source 
Now we search in priority with the GUI language, and then the
language(s) specified in the LANGUAGES environment variable.
Preoviously, the GUI language would only be considered when
LANGUAGES was not set (which was a bug).

Take this opportunity to remove old compatibility code from 2007.
