Remove unwanted AI traffic models/liveries

I wish each aircraft could have a toggle, in sim, to have it available for use in AI or static aircraft generation.

I know I can edit this manually in the aircraft.cfg, but it would be nice to have this accessible in the sim itself, so users could simply select a checkbox - available for AI.

If I’m flying a Spitfire for example, I don’t necessarily want to see spitfires, or stearmans in different airports. My aircraft is fairly unique in this example.
