Note: all spells with effect expect additional code for redirection reset.
Until code adding redirection work longer that expected.

Patch partly rewrited with move new data into HostileRefManager
and added redirection to threatAssist. Also bug fixed with
redirection threat to unit not in hostile list yet.
* Add single arg version Unit::AddThreat for just adding to threat list.
* Req. provide schollmask and crit flag for any real threat value for proper threats mod apply.
* Send crit flag in DealDamage as MELEE_HIT_CRIT for spell damage for later send to threat call.
* For not affected by modifiers threat values use SPELL_SCHOOL_MASK_NONE.
* Implement aura SPELL_AURA_MOD_CRITICAL_THREAT (used only in itemset 529 effect).
