Wrote create-player (though still buggy)

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

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.

Started work on the interpreter. ...

More code added to util.lisp, changed ATL syntax to suit Lisp better.

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