/** The mob is agressive toward specific mobtypes (mobTodo), or toward the player.
 *

Connections to other behaviors:
 - The mob should also have a cBehaviorAttacker, otherwise this behavior will not work.
 - This behavior does not make sense in combination with BehaviorCoward or cBehaviorBrave.

Special connections:
 - Relies on cMonster::GetAttackerBehavior to obtain the attacker behavior and alter its target.
