 * Manually Apply Damage to a unit (can cause lethal damage)
 * NOTE: because of caching, this will not have instant effects (~3 frame delay)
 *
 * Arguments:
 * 0: The Unit <OBJECT>
 * 1: Damage to Add <NUMBER>
 * 2: Body part ("Head", "Body", "LeftArm", "RightArm", "LeftLeg", "RightLeg") <STRING>
 * 3: Projectile Type <STRING>
 * 4: Source <OBJECT>
 *
 * Return Value:
 * Successful <BOOL>
 *
 * Example:
 * [player, 0.8, "rightleg", "bullet"] call ace_medical_fnc_addDamageToUnit
 * [cursorTarget, 1, "body", "stab", player] call ace_medical_fnc_addDamageToUnit
 *
 * Public: Yes
