Beutepanzer rear guns to AA

Since two gunners in rear sponsons never see ground combat, this mod arms them with machine guns and gets them to target aircraft. This gives a nice dense 'trench fire' effect if you fly low behind the panzers in an allied craft.

The rest of the tank's guns still work against ground targets.
