/*
 * Author: KoffeinFlummi
 *
 * My very own setHitPointDamage since BIS's one is buggy when affecting a remote unit.
 * It also doesn't change the overall damage. This does.
 *
 * Arguments:
 * 0: unit
 * 1: selection
 * 2: damage
 * 3: disable overall damage adjustment (optional)
 *
 * Return Value:
 * -
