Air disconnect safety

[jonpas]

Safety system for pilot (or co-pilot if in control) when he gets disconnected, so all crew on-board and the airframe are not lost due to technical issues.

• Freeze helicopter/plane mid-air (disable simulation, hide object)
• Place player back into seat on reload if spawned within certain distance of the frozen airframe
  • Maybe distance is not best idea, as Arma sometimes doesn't register right away (but then freezing is also a problem)
  • Unfreeze as interaction (to make sure pilot is fully loaded in)
• Allow switching from any slot to pilot slot to unfreeze and continue (has to be safe, so sub-item in interaction)

Fits air_security component.

Can integrate with Apollo persistence vehicle passenger saving (once that is implemented). Might as well do that as it's a similar system, except vehicles on the ground (touching ground or below 1m ATL) - only stop those (or slow them down) so they don't crash.

Entire persistence could work in the following manner:

• Save vehicle object (varName) on player save (and position in vehicle)
  • varName is Chronos varName if vehicle is Chronos tracked (QEGVAR(apollo,vehicleID))
  • varName is varName given on save and added to list of temp-saved object relations (setVehicleVarName "TAC_TEMP_5" without vehicleID), those don't get deleted until session end to avoid removal handling - (single session vehicle anyways)
• On load if vehicle still alive, place player in:
  • <special handling if vehicle frozen in-air - read above>
  • Same position if free
  • Any remaining free position
  • Position of disconnect (avoids spawning in dangerous areas, Zeus can still teleport) ~Near vehicle if not free~
