Updated Stalingrad '42 ALT art / scenario pack

[Volcano Man]

No, there should never be a problem with updating in mid game (this goes for all the ALT updates). I try to go through great care as not to ruin anyones games, of course I am not perfect but I try to make seperate OOBs when a change is made that will affect a PBEM game (in which case you will not see a certain change take effect unless you restart).
