[L2NPC] Privates respawn bug

[Master Toma]

Original L2NPC bug.

When spawn first time (load npcpos), leader + 2 privates spawn correctly

When you kill all privates, but leader is alive show npc maker count as "2" when should to be "1"

I you kill leader now, wait spawn again party monster, here begin problem.
Only spawn leader + 1 private (but count is 3), so than we have missing one private

npc maker count isn't decreased correctly.

For simplified test, use attached ai and npcpos

Some time also mobs are spawned under the geodata (fall down)

Fix in L2NPC engine (check for dead leader) + fix in npcpos.txt: setup respawn time to 0 (no respawn)
