IFF test results (all similar sexps were changed the same way).  

All ships started as freindly.  Test with event set to 5 second delay or just true results the same. 


Ship	Arrival time:	Change type:	45 seconds	Change	65 seconds	At Respawn
------------------------------------------------------------------------------------------
A1	Start		Each ship	Friendly	A2	Friendly	Friendly
A2					Hostile		to 	Neutral		Friendly
A3					Hostile	      Neutral	Hostile		Friendly

B1	10 seconds	Wing then	Friendly	Wing	Neutral		Neutral	
B2			first ship	Hostile		to	Neutral		Neutral
B3			changed back	Hostile	      Neutral	Neutral		Neutral

C1	Start		Wing then	Friendly	Wing	Neutral		Neutral
C2			frist ship	Hostile		to	Neutral		Neutral
C3			changed back	Hostile	      Neutral	Neutral		Neutral

D1	30 seconds	Each ship	Friendly	D3	Friendly	Freindly
D2					Hostile		to	Hostile		Hostile
D3					Hostile	      Neutral	Neutral		Hostile


So changes to wing change all waves if the wing has arrived or not.
Changes to ships depend on if the ship is in mission or not.  
If in mission only the current ships are changed not the ship in the following waves
If wing hasn't arrived yet all wave are set.

Now before the bug fix the only thing that should be different are are wings that has not
arrived yet.  In this test that would have resulted in B wing being all Friendly
at 45 seconds.  Rest of the items would have been processed the same way.  

Other sexps using OSWPT_TYPE_WING: should not be effected as the wings that have not arrived 
yet are processed based on new OSWPT_TYPE_FUTURE_WING:  

Sexps effected:

change-iff
change-iff-color
