they basicaly should
*autocast 22011
*give player after gossiphello buff 2584
*port players away to another spiritguides, when they die
so this can be done by a script

* Move CMSG_MOVE_KNOCK_BACK_ACK (player case) to Unit::KnockBackFrom
* Implement creature case, most at hack way currently :(
Need information about expected server packet, and possible some disorientation movegen apply at short time.
* In adition of spell 781 implement related creature versions.
* Fixed warnings spawn at reading CMSG_MOVE_KNOCK_BACK_ACK, CMSG_MOVE_HOVER_ACK, CMSG_MOVE_WATER_WALK_ACK.
* Added basic infrastructure for visibility update in case difference player and current view point.
Just for note: seletect additional arg way beacuse repeatable search object will slow but store pointer will not safe,
so use middle case: get view point pointer early as possible at visibility updates.
* Implement dynamic object and creature activisation while it's target of far sight spell effect
* Use this for SPELL_AURA_BIND_SIGHT, SPELL_AURA_FAR_SIGHT and SPELL_EFFECT_ADD_FARSIGHT.
* Note2: some spyglass like spells let look _around_ at long distance, this hard implement in current grid loading system
Without additional changes and not implemented (you will see empty area without creatures in likes case)

* Use counter for aura uses lock for recursivly mark as used in some cases.
* At aura remove add aura to deleting delayed auras list for aura target.

* Use new aura delete locking for simplify proc spell event code.
* Prevent apply aura boost spells if aura deleted while adding to target by triggered spells.
* Re-implement aura list updating at auras update for target to better way skip
removed from aura list auras while auras update.
* Not set owner for will summoned gameobjects.
