/**
 * fn_playInjuredSound.sqf
 * @Descr: Play the injured sound for a unit if the unit is damaged. The sound broadcasted across MP. 
 * Will not play if the unit has already played a sound within to close a time frame.
 * Delay: With minimal damage (below 1), the delay is (10 + random(50)) seconds. Otherwise it is 60 seconds / damage. 
 * 
 * @Author: Glowbal
 *
 * @Arguments: [unit OBJECT]
 * @Return: nil
 * @PublicAPI: false
