- Added the MF2_PASSMOBJ for P_Thing_Spawn() from January 4, 2003, to

DLevelScript::DoSpawn().
- Changed VectorNormalize() (and VectorNormalize2) to use doubles for storing
  the vector lengths, fixing desyncs between GCC/VC++ games that happened
  because the two compilers produced slightly different results for some
  slopes. GCC kept them in registers, so they were never truncated to floats.
  VC++ stored them to memory and reloaded them in order to truncate them to
  the defined precision. Lesson learned: Floating point numbers in local
  variables should always be doubles to produce the best code with VC++ that
  has the best chance of matching GCC's default behavior.
- Removed netget and netsend function pointers. PacketGet and PacketSend are
  now called directly.
- Fixed: Watching a demo from the point of view of someone other than the
  first player could cause a crash when the demo ended.
- Removed invcount from the expression evaluator at Grubber's suggestion,
  because it doesn't work.
- Fixed: vid_nowidescreen should fire off setsizeneeded so that changes to it
  can happen immediately instead of at the next resolution change.

 - Modified the way autosaves are done. Instead of setting gameaction to
   ga_autosave, write DEM_CHECKAUTOSAVE to the net stream. When this is
   processed, it will check if it's okay to do an autosave. If it is, it writes
