2.4 patch 1b: (Brandon Gillespie / Rob Forsman)

   * Observer bug fix
   * even better setup script.  Note: it is now in the NETREKDIR, not
     NETREKDIR/src (so you can remove NETREKDIR/src/setup).
   * Galaxy Generator #6.  This isn't really more than Heath's Galaxy
     Generator #3 with a few tweaks on the settings, but I made it
     another generator rather than a define in config.h so you can use
     both generators.
   * Made the robot actually say something in binary (before he didn't)
   * Fixed the rank exemption for GODLIKE people (top to ranks of royalty)
     on ships.  Before it was backwards (i.e. Wesleys were exempt).
   * Exempted GODLIKE people from cluechecker #2
   * Added the RSA exemption file (Rob's)
   * fixed the WE ARE CLOSED message (wasn't displaying because line was
     too long).

2.4 patch 2: (Brandon Gillespie)

   * Adjusted default values per PLC decision
   * fixed some problems in the setup script
   * fixed a minor bug with announcing the end of a game.

2.4 patch 4: (Mike McGrath)

   * Added support for terrain features.
   * Implemented asteroids using the new terrain stuff.

2.4 patch 5: (Bob Glamm)

   * I actually did the coding for this one.
   * Socket code for Mike's terrains (nebula/asteroids)

2.4 patch 6: (Mike McGrath)
 
   * Asteroids are completely finished -- fields have different
     densities, thicknesses, distances from their parent star, etc.
   * Asteroids affect ships, in addition to weapons.
   * New PLC ship values turned default.
