Performance Improvement: hpmeter

whenever a character's hp was modified (e.g. damage/heal), clif_hpmeter would look for nearby characters with the PC_PERM_VIEW_HPMETER permission (foreachinarea operation), and since most of the time there isn't such a char nearby it would needlessly consume processing power, now hpmeter is only triggered when there are actual  need (when a character with such capabilities is within the map). as little as this may look like, its a mega boost for damage-intensive areas e.g. woe, whereas a single AoE damaging 10 people would, without this, trigger foreachinarea 10 times one very hit.
