Fix Pathfinding and Other AI Blunders

[Bliep]

I came to the conclusion that DMS has no (skilled) AI programmer. I tested some of their other stuff now and it is as terrible as this one.

If you want to continue playing cause you forked out 50 euro's or whatever currency you use then I advise you to save a lot and use direct action control to throw satchel charges. Also make sure you cook your frag grenades in direct control by holding the right mouse before releasing, makes sure the AI can't dive and survive.
