Add helicopter training tools

[JoramD]

As title states add helicopter training tools

Current ideas:

• Random LZ generator (just pop a random smoke somewhere and send grid to pilot)
• Apply damage
  • Like medical functionality allow to damage specific parts
  • Including random part selection
  • Allow instant damage or random timer
• People simulation, add "people" by script to simulate weight

Easiest would be to enable when someone is in air vehicle.
Basing this off of Ian's personal little training mission

Idea update:
Add CBA setting to enable on Olympus and Icarus, and check if player is in helicopter.
Limited damage types: No point in doing damage to every part, only focus on engine, rotor, tailrotor

Same thing as we want in Icarus?

Maybe we should add those 2 systems to TAC Mods so we can just use them in both missions.
