* In Opposing Force pitdrone spawned via monstermaker did not have spikes
* That's probably a bug, because number of spikes is set in level editor,
* so spawned pitdrones always had 0 spikes.
* Having no spikes after spawn also prevented spike reloading.
* Those who want to keep original Opposing Force behavior can set this constant to zero.
