Randy Heit 60472c2b45 - Fixed: DThinker::SerializeAll() did not serialize any thinkers in the
FreshThinkers lists. These thinkers would still be saved in the savegame if
  there were other references to them, but they would not go in any thinker
  lists when loading the savegame. An easy way to exercise this bug is to
  give yourself something new with the console and then save the game right
  away without closing the console by using the "save" command. The item
  would be stored in the savegame thanks to its presence in the Inventory
  list, but it wouldn't be in a thinker list when the game was reloaded
  because it was still in the FreshThinkers list when the game was saved.
