Re-wrote plotsprites to use slices internally. The code is shorter now, and should
resolve bug 701 (the crash with "clone sprite")

I have not made any outward changes to the plotscripting interface (at the moment)

Also added a helper function to slices.bas, ChangeSpriteSlice() which lets you alter a sprite 
slice's properties without needing to manually cast the slice's SpriteData member
