[New Feature] AirArmor

[DeathFishAtEase]

Description:

There are different altitude settings for air units in many mods. For example, some fighters can attack only with special air defense weapons, They are discriminated by armor. But if these units land on the ground, there will be a very embarrassing scene: ordinary ground units can't fire on it! It's too unreasonable.
So I hope to change the status of the unit according to the position of the unit

(Of course, you only need to distinguish between the ground and the air
It don't need to have a variety of forms according to different altitude segments. Although it's fine, it's too cumbersome)

Possible Implementation:

in rulesmd.ini
[TechnoType]
AirArmor=(armortype)
;Armor when an object is in the air
;def=Armor=

I prefer to add a new one called Convert.Air label, It can work with ares's Convert.[Land|Water]= cooperate with each other, and only one more distinction of air state is needed
but
In consideration of Convert.[Land|Water] has effectively been reimplemented on Ares side and thus cannot be altered in Phobos(same as Dominator superweapon). you can also distinguish the air force at different heights by adding like AirArmor=(armortype), but I think it would be better to expand the Convert logic that already exists in the Ares
