Remove the requierment for enemy in strafe zone.

[Gunfreak]

So I love the new strafe order for the AI, however they only seem to attack if there is an enemy in the area set to be strafed. 

They do not attack if there is no enemy to actually attack.

1. Remove that requirement, if I set down strafe they will strafe the empty sea if I want them to.
2. When I say they should use up ALL stores/ammo they should, they got 20 seconds of cannon fire, they should use up that ammo if I demand so, if they got 10 or 30 rockets they should expend ALL rockets, I'm the god of the AI and they should do as I say.
3. let me decide the strafe distance, If I want 200 rounds down a 20 feet strip I should get that, If I want a 1200 round downs a 2000 feet strip I should be able to get that.
