Some refactoring in world/game-object, expanded commandline parameter parsing.

Did some planning on how to proceed from here, started on the networking module.

Refactored game command system, added 'player' command. ...

Version 0.1 is now ready - ATL files are parsed properly, the world
and the player are created, and the player can move around inside
the world. The first stage of a long journey is hereby completed!
:-)

Finished the 'goto', 'place' and 'help' commands. ...

I noticed that the code is starting to look quite crufty - time
for a clean up, I think...

Started implementing in-game commands, expanded test world.

Finally got create-player working.

Created an ATL-mode for Emacs and expanded the test world.

Wrote create-player (though still buggy)

Saved a lot of code by writing build-symbol, started on client module.

Enabled Lisp extension files to be loaded from ATL source file. ...

Also added option to show license to interactive start menu, and
various small bug fixes/additions.

Parsing an ATL file now actually builds the *world*.

Merged in master (to obtain Python code), added commandline parameter parsing.

Enabled recursive loading of ATL files, implemented option command behaviour. ...

The latter caused many headaches, and great joy in its completion :D

Integrated interpreter.lisp with atlantis.lisp, various bug fixes.

More work on util.lisp, changed license to MIT.
