* further remove audio_GetIDFromStr from src/aud.c and rename audioID_GetIDFromStr (from audio_id.c) to audio_GetIDFromStr
* also changed calling method of audio_GetIDFromStr, now it returns its retrieved value (ID index number) rather than writing it in a pointer given as parameter
PS MSVC project might be broken, I don't have it so can't check nor fix it
