Core/Spell: Last work on Shadows Fate

 - Shadows Fate can now be applied by more than just one player at the same
   time. So on everyone who hits the unit the credit spell with the visual
   will be casted on death.
- The AOE credit spells for the three infusion quests will be casted by
  the boss once. If this would be done on proc, these AOE spells could be
  casted up to 25 times.
  -> 25 AOE credit spells plus 25 Soul Feast credit spells equals Sh**
