[Vanilla Enhancement] Customized transport plane for teams

[Fly-Star-him]

You can now use ParaDropAircraft to specify a new transport aircraft type for teams with Droppod=yes, which will override the global settings for Ares and Vanilla.

现在你可以使用ParaDropAircraft为Droppod=yes的作战小队指定新的运输机类型，它会覆盖Ares和Vanilla的全局设置。

In aimd.ini / mycampaign.map:

[SOMETEAMTYPE]      ; TeamType
ParaDropAircraft=      ; AircraftType
