/** Grants breeding capabilities to the mob.
Recommended combination with cBehaviorItemFollower.

Connections to other behaviors:
 - If the mob also has cBehaviorPet, this behavior is suppressed unless the mob has an owner.

Special connections:
 - Relies on the polymorphic cMonster::GetBreedingItems function to determine the breeding items.
