Updated VectorStorm and Munchers builds

I’ve just updated Win32 and OSX builds of the VectorStorm test games and Muncher’s Labyrinth, to support configurable gamepads. (Including most of the “Stage two” features I mentioned before).

As it turns out, SDL doesn’t provide support for the ‘hotplug’ feature I wanted to implement, so I had to drop that. Hopefully it’ll be included in the SDL 1.3 series, when that eventuates.
