Use PXtone in Game Maker

I've just spent the afternoon making a DLL that allows Game Maker to use the PXtone sound engine.

The included example is for GM6, but the script files have also been included so that GM5 users can make use of it as well. Seems to work in GM7, too, so that's good.

I don't really know how many people here use game maker, but I figured I'd put it here just in case I'm not the only one.

There may or may not be bugs, I haven't had any problems so far, but let me know if you run into anything.
