drawimgaslight and setopac

[haunter]

Two new commands:

drawimgaslight index;

-This would be the same as drawaslight but it would work for showimg's

setopac opacity;

Something like the alpha in setcoloreffect, but instead of changing the ammount of black in the image, it would change the opacity(sp) making it possible to use images to make shadows w/o having to do the reverse thingy...
