When a trader is being persuaded to turn around via space chat the stats screen 
gets skipped. That's good :)

This behaviour should also apply when attacking a normal mission unrelated 
trader or an infected trader. If he get's destroyed or just slipps through, 
either way the screen gets skipped in DOS IG. A stats screen is only used for 
"real" battles (and then it's making sense because it can actually show some 
stats) or other mission related fights (i.e. the virus carriers).

This way we get rid of this strange construct "You've won the battle - the 
trader slipped through" once and for all :)
