Load last world state from save file, not from re-stepping record file.

Load last world state from save file, not from re-stepping record file.

Re-wrote large chunks of code dealing with server message parsing and
file parsing in general. Introduced "god commands" (manipulating the
game state beyond player actor control) that direct the re-generation of
the game state when loading the save file. Introduced a module
"hardcoded_strings" to store strings re-used and expected among various
modules.
