 - works exactly the same as message_str, except you get messages from files in "text\<language>\game\" directory
 - use GAME_MSG_* defines or mstr_* macros from sfall.h to use specific msg file
 - Additional game msg files added by ExtraGameMsgFileList setting will have consecutive fileIds assigned beginning from 0x2000 to 0x2FFF. (e.g. if you set ExtraGameMsgFileList=foo,bar in ddraw.ini, foo.msg will be associated with 0x2000 and bar.msg with 0x2001.)
