[1.21i] Inconsistency in aircraft listed ammo usage

[Soar_Slitherine]

The listed anti-air ammo usage for aircraft is now different compared to using the same weapon against ground targets. For example, an aircraft with a Twin Heavy Advanced MG has its ammo usage in Blueprints and Models -> Op.Cost listed as 30/6. The first number appears the be 10 times weapon's base ammo cost per round, and the second number is 10 times the weapon's *old* base ammo cost per round.

In previous versions, if the ammo cost of bombs was deducted from the first number, the result was equal to the second number.
