Weird Worlds Mac OS X patch for testing

[Fingers]

The universal binary will not happen anytime soon. If I understand the situation correctly, there's some kind of a problem getting OpenAL to work with universal binaries.

I'm going to use my own SDL-based sound system in our future games, and there's a possibility that I'll retrofit it to Weird Worlds... which may make the universal binary easier to do. In any case it'll be at least a couple of months before this happens, as it's kind of a big change in the code.
