COMMITTED: SE_SpellTrigger(formerly SE_LifeshardChance)

[Caryatis]

wish we could edit longer... there was a slight error in that you could trigger bark at the moon type spells twice if lucky... this should fix that while allowing spells like annhilate to proc twice.

void Mob::TrySpellTrigger(Mob *target, uint32 spell_id)
{
	if(target == NULL || !IsValidSpell(spell_id))
	{
		return;
	}
	int spell_trig = 100;
	int triggered = 0;
	for(int i = 0; i < EFFECT_COUNT; i++)
	{
		if (spells[spell_id].effectid[i] == SE_SpellTrigger)
		{
			// If we have failed a check already, the spell_trig variable will be set lower than 100, so if they add to 100 then the second chance is guaranteed.
			if (spells[spell_id].base[i] + spell_trig == 100) 
			{
				SpellOnTarget(spells[spell_id].base2[i], target);
				break;
			}
			// if we have successfully cast a spell that has 2 chances that add to 100% then stop here
			else if (triggered == 1 && spells[spell_id].base[i] + spell_trig == 100) {
				break;
			}
			if(MakeRandomInt(0, 100) <= spells[spell_id].base[i]) 
			{
				SpellOnTarget(spells[spell_id].base2[i], target);
				int triggered = 1;
			}
			else {
				spell_trig = spells[spell_id].base[i];
			}
		}
	}
