Aircraft/MPCarrier/Systems/MPCarriers.nas: auto attach to carriers if /sim/mp-carriers/auto-attach is true.
We only auto-attach if carrier has just appeared, and there is exactly one instance of the carrier type, and /sim/mp-carriers/auto-attach is true.
Disabled by default. To enable, use:
--prop:bool:/sim/mp-carriers/auto-attach=true
