Flag for A_FaceTarget

[GhostKillahZero]

FAF_CLOSEST - like the name implies, actors with this flag will target other actors closest to them.

The function is called "A_FaceTarget", i.e. the point is to face the TARGET, not some random actor. What's the use case?

[Matt]

Seems like the intent is that the caller would *find* the nearest actor and target it.

I'd rather just use a BlockThingsIterator there myself.

Or make a different function. Just a quick note that although this may sound simple, it can end up a costly operation because the only way to do it is a blockmap search that's spreading ever further out if nothing is found.
