Buff machine gun. APC can shoot at ground now. 

Humvee and Nod Buggy get buff to their machine gun--it's now the same power as Jeep's in ORA.

APC gun now shoots at ground instead of just air. Reduced range from 7 to 5 as a result.
This should give a soft counter to enemy vehicles if the player decides not to play with tanks in the early game.
