FARP/CCP/Airborne: Allow spawn on carriers

[10Dozen]

Something like this to track that marker position is over deck (_iObj is present and _iPos is above sea level)

fnc_checkIsOnDeck = {
	params ["_mrk"];
	
	private _pos = getMarkerPos _mrk;
	private _objects = lineIntersectsSurfaces [
		[_pos # 0, _pos # 1, 100],
		[_pos # 0, _pos # 1, -15],
		objNull,
		objNull,
		true, 5, "GEOM"
	];
	
	dzn_LOG = [];
	{
		_x params ["_iPos","_surfNormal","_iObj","_pObj"];
		dzn_LOG pushBack _x;
		systemChat str(_x);
	} forEach _objects;

	dzn_LOG
};
