Remove monster spawn when unloadnpcfile

Edit: Can be closed. I've found another solution.

Could someone be so kind as to implement the rAthena commit for Hercules?
It is extremely useful that monsters are removed when an NPC gets unloaded.
This makes certain events and similar systems much more convenient.
