Aaron Kimbrell 425b913848 feat(physics): movement blockers the server's movers can't walk through ...

Enemies are moved along navmesh paths without collision, so a wall only stops
them if their path stops at it. dpWorld now keeps a list of such walls, each
with the collision filter it blocks with, and cuts a path where it first walks
into one (a little short of the wall; a mover inside one can walk out).

Which objects block comes from data (dpMovementBlockers::BlockingFilter):
- navmesh carvers (navmesh_carver in the level config, which the client reads
  with add_to_navmesh and carver_only) block every mover;
- solid objects whose collision group touches enemies and not players (group 18,
  e.g. "FV - Enemy Blocking Volume", "PR - Pet Blocker") block what that group
  touches.

dpShapeBox gains SegmentEntry, a segment test against the rotated box.
