Buff Orca dmg. vs. Heavy. Nerf vs. Air

Orca damage vs. heavy currently is pretty abysmal. Needs buff to define unit as anti-vehicle (instead of being equal to Apache vs. vehicles/armor).

Orca nerfed a bit vs. air to put it on even footing with Apache in air-to-air combat.

ROF slightly increased.
