Function will return a cast result, with fail reasons if spell can not be casted (can be used to take alternative action). Please note this is not a full list of cast fail errors/reasons, but will cover a few basic errors that may occur.
The virtual function CanCastSpell() may be adjusted for custom needs from script library if not the default is sufficient.

* Use AI::AttackStart calls only in case explicit request creature attack from core or AI code "attack it if can".
Like taunt, pet handler attack command.
* Use AI::AttackedBy for reaction at hostile action "do something at hostile action"
Like non-dot damage, swing, negative spell landing, or fade fear/etc.
And provided by default call AttackStart if no current target.
This fix some problems, like:
* Civilian will react propertly at attack by another creature (not pet or player).
* Will not cases (at least triggred by core) when attack target start run to attacker before any real hostile action apply.
Also send pointer to AI constructors ans mark constructors as explicit.
This changes allow move now some generic often used AI code to CreatureAI helper functions.
