Subject: [PATCH] - Enable 'language' feature on unix targets.

The sdl version of the function 'SetLanguageIDs' is very limited, comparing to the win32 counterpart, as it will try to accept only the language codes (ie 'enu', 'fr', 'ptb', etc). If a different string is provided, zdoom will default its language to English.
