Aaron Kimbrell 5d3c2e6f9a fix: filter physics volumes like the client's collision groups
Volumes on the server touched far more than in the client:

- An enemy's body in the physics world was a sphere the size of its aggro
  radius, so trigger and damage volumes caught enemies from far away
  (Cavalry Hill enemies taking damage on spawn). It is now the enemy's
  own radius and collision group from its physics component.
- Trigger volumes ignored their collision group and caught everything.
  dpEntity now filters with the client's collision filter
  (PeCollisionFilter, 1.10.64 0x00fb6940, group table from 0x00fcf9a0):
  POI walls ignore enemies, threat clearing walls ignore players, and
  so on. The aggro sensor keeps seeing only players.
- Rotated boxes were tested as the axis aligned box around them, which
  for a turned wall covers a big square (the AG survival boundary).
  Sphere and point tests now use the box's own axes.

Proximity monitors take an optional collision group like live's
SetProximityRadius; the AM shield generators use live's (10 finds
enemies, 1 finds players).
