Adjust Photon Seeker logic

[srmalloy]

Is it possible to tweak the way that Peacebringer Photon Seekers are summoned/move so that they don't appear stacked on top of each other and remain that way until they decide to kamiikaze whichever random enemy mob attracts their attention? It kind of defeats the purpose of being able to name them if all you see above the Photon Seeker glow is a multiply-overlaid garble. It's a fairlly minor thing, but other uncontrollable pets, like fire imps and seeker drones, spawn away from each other, so it should be possible for Photon Seekers as well.
