"emptyPositions" is a great command for finding unoccupied seats in a vehicle. At the moment supported positions are

"Driver"
"Commander"
"Gunner"
"Cargo"

But here is the problem. Vehicles with 2 gunners like some helicopters will report only 1 gunner position because another gunner position is a turret position. For vehicles liek this finding out all available empty seats is a pain in a butt.

Proposed param "Turret" should return array of turret paths, for example

veh emptyPositions "Turret"; //[[0],[0,0],[1]];

would also be extremely useful for finding all turrets for a vehicle, instead of shifting through configs.
