new area trigger bit

[Avenger]

The bit which was called "override?" in dltcep based on vague descriptions is now fully tested.

 

It is used in SoA and ToB.

The original SoA seems to use this bit only for area triggers, it set up an alternate point to walk to instead of the default point.

 

It is possible to use this alternate point for info triggers too, in this case the WalkedToTrigger trigger is useful. This latter functionality may be existing only in ToB.

 

The alternate point is stored on two shorts right after the script resref field.

Check out this example from ar4500 (pocket plane)

The info flag is set to 0x400, and the use point fields are filled after the script resref.
