Tweak Familiars (#1162)

# Description

Default following distance for Psi Familiars was apparently >10 meters,
making them have an extremely hard time following their Master in actual
live servers. This PR tweaks them to have a maximum 3 meter following
distance, the same as Rat Servants actually, so that they can more
consistently follow their Master.

# Changelog

:cl:
- tweak: Changed the default "Following distance" of Psionic Familiars
from 10 meters to 3 meters, so that they don't have an ungodly hard time
keeping up with their Master.
