Replaced parser with code.

It was an experiment in insanity to implicitly write up an "impoverished"
language to define various game objects.  I ended up spending a crazy
amount of time just parsing data that was easier to represent, modify, and
read in Racket syntax (s-expressions.)

All armor weapons skills spells characters and foes have been directly
encoded.  All parsing code has been removed, as it is no longer necessary.
