Astromech droid

WIP An astromech droid is a passive droid mob.

=Drops= An astromech droid drops 1–3 experience points when destroyed by a player or hound.

=Behavior= Astromech droids wander aimlessly. When falling, they use their rocket thrusters to fall slowly, thus they are immune to fall damage. However, they avoid falling off cliffs. They also use them to climb up stairs and stay on the water surface when swimming.

Astromech droids are attacked by Loth-cats, pikobis, and tookas. When harmed, they flee around.

Astromech droids follow nearby players who are holding a droid caller.
