Fixed respawn bug in AI_BALANCER + Scheduler bug

AI_BALANCER respawns back the AI. Bug was in the FSM. In a transition,
when states are the same, the events SHOULD execute.
Added spawn delay interval option API SetSpawnInterval().
Bug that prevented AI_BALANCER to start if multiple AI_BALANCERs is also
fixed.
Fixed bug in scheduler dispatcher. Multiple schedules for the same
scheduler work now too!
