Core/Spells: add an other condition to SpellInfo::NeedsToBeTriggeredByCaster to correct spells with are wrongly triggered by target instead of caster

- convert archavons rock shards to spellscript (now it works properly)
- add a spellscript for one spell that can't be corrected by this (and delete the sai hack, now i uses the correct spell)
