CD/talkie versions about derclou

I do not have access to the english CD version to test with. There are some command line option switches.
It might also be the case that the version detection algorithm is failing for some reason or that it can't find the path to the voices. I think I stubbed out some of the DOS specific CD code so something might not be implemented. Check cdrom/cdrom.c.

All the functions are disabled. I think the original used audio tracks, according this archived copy of the game.
