Change XYZ Quaking from Major Cooke

Browse source 
- Relative quakes are different from other quakes; all quakes affecting
  the camera do not become relative if one of them is relative.
- Use a single function call to get quake visual parameters instead of four.
- Thrust things in a psuedo-ellipse if they're inside a damaging quake whose
  IntensityX != IntensityY.
- Don't break old savegames.
