The nav trace was measuring the wrong five seconds

Browse Source 
It sampled the first five sweeps, which run while the mission is still
coming up and nothing has registered with the renderer yet. So it reported
"0 static, 0 moving" on a POD, whose map demonstrably works - and I took
that reading at face value and concluded the map was broken for everyone.
It was the instrument, not the game.

Now sampled on a clock like the ranking trace, every five seconds, and the
bounds line repeats too so the centre can be seen tracking. The real
baseline from a pod race:

  CamLog: nav in bounds - 0 static, 0 moving      (first sample, loading)
  CamLog: nav in bounds - 44 static, 1 moving     (running, and stays)

44 static is the track, 1 moving is the player, and the centre walks with
the vehicle. That is what a working nav display looks like, so a camera
station can now be compared against something real rather than against a
startup artefact.

Found by putting the pod's map on screen next to its own trace, which is
what should have happened before the first conclusion.
