Make Beepsky feared again

[Superlagg]

Part of his weakness lies in how critters seem to work. They choose a place to go, path over to it, then after a while do their attack and hope their target is still in range. Kinda seems like way it works is that it queues up its attack, target, and place-to-go-to, puts in a delay to give it time to pathfind around, then execute the attack proc thing once that delay ends. Maybe to save on checks or something? At any rate, critter AI in general could use some robustening, either shortening that delay or including some checks-if-target-there as it moves.

...and then include that only on Beepsky.
