Core/Misc: fix interaction of spells like Shadowmeld with Threat reducing effects

- SPELL_AURA_MOD_TOTAL_THREAT should be temporary and not added/subtracted from total, only computed
- Cleanup of reference related code
- Kill getLast() and reverse iterator obsevers, LinkedList iterator can't be used as a standard reverse_iterator (ie with operator++). They weren't used anyways
