/*
 * Author: Garth 'L-H' de Wet
 * Causes the unit to detonate the passed explosive.
 *
 * Arguments:
 * 0: Unit <OBJECT>
 * 1: Max range (-1 to ignore) <NUMBER>
 * 2: Explosive <ARRAY>
 *     0: Explosive <OBJECT>
 *     1: Fuse time <NUMBER>
 * 3: Trigger Item Classname <STRING>
 *
 * Return Value:
 * None
 *
 * Example:
 * [player, 100, [Explosive, 1], "ACE_Clacker"] call ACE_Explosives_fnc_detonateExplosive; // has to be within range
 * [player, -1, [Explosive, 1], "ACE_Cellphone"] call ACE_Explosives_fnc_detonateExplosive; // range ignored.
 *
 * Public: Yes
