Notes

• The change IFF sexp can be used by mission designers so that when called, it will change the IFF of a given ship so that it can effectively change allegiance. It can also be used to change the Player's IFF simulating desertion or Command's wrath at messing up in some way.
• The Source Code Project has added a "Traitor" IFF, which is to be preferred over "Hostile" for mission-generated traitor states. It will trigger the table-controlled traitor debriefing.
