Compute fog in ProcessVertices, increase supported light count in ddraw

The lighting in _ProcessVertices has now been implemented, but this game needs
a bit more than that for correct rendering, that is, fog coordinate computation
and more active lights supported. Yes, without that it is all black or so with
the current git. I am going to suggest the patches for that upstream soon and I
hope it will appear in Wine after a short while. Meanwhile I am attaching those
patches here in case anyone wants to try that.
