Add attacker into target attacklist before attack event notification.

Plus: now players can't use non-damage skills for luring mobs.
Minus: skill "Lure" broken too :)

Please remember what during server start mobs spawn all in once and their knownlist is empty. So first time after start mobs will not use faction calls.
For bosses IMHO we will need to add minions into knownlist manually.
