Matthew Bauer cdd0ac7e54 dwarf-fortress: support older versions as well
game.json now contains a dictionary of old game hashes. I have added
them for the last 3 releases.

- add script to generate hashes

  Makes it much easier to update game.json file.

- add updateScript meta

  This adds some info on the ./update.sh updateScript now available.

- cleanup updateScript

  - Add some more systems
  - Correctly detect source extensions (.zip or .tar.bz2)
  - Proper bash quoting

- fix update.sh

  - correctly detect latest df version
  - append to game.json instead of overwriting it

- update hashes for 44.12
