Initial Pathfinder encoding commit

This is incomplete, obviously. Just saving my work
with this commit. I deleted that useless
'new_engine.json' file as well.

I'll try to finish the engine with the next commit
and the beginner box content with the one after
that.
Next big step in encoding Pathfinder

This commit sees the basic skeleton
of the game encoded. One can't say
that the engine is done since all
of the rules aren't written out.
The structure of the game is there
though, in the JSON.

A bunch of content is done too. All of
the beginner box classes, races, and
equipment are done. Next commit should
include spells / skills / feats. Then
another commit can be enemies. Text
for rules and descriptions will come
last.
Renamed some files, changed priorities

This commit properly names the Pathfinder
directory; I want to make a distinction
between the complete game and the
beginner box.

This commit also represents a switch in
priorities. My last commit (mistakenly)
predicted that the next series of commits
would all be content encoding for
Pathfinder. Circumstances have made it such
that this is not the best use of time.
