Handle ace_cargo_canLoad set to scalar

[PabstMirror]

var ace_cargo_canLoad used to be 0/1
some addons are still setting to scalar

e.g. r3f-logistics does

		_object setVariable ['ace_dragging_canCarry', false];
		_object setVariable ['ace_dragging_canDrag', false];
		_object setVariable ['ace_cargo_canLoad', 0];

Throws error

  Error ||: Type Number, expected Bool,code
 File z\ace\addons\cargo\functions\fnc_initObject.sqf, line 13

Good solution 👍

It definitely makes more sense as a bool to me based on the variable name.
