Fixes hand positions on the Dean + new costume

So it was my first time working on a costume for the Dean, and I noticed that he slid back while attacking barehanded, and his wield-walk was REALLY jerky going in one of the directions, so with @bucketh3ad's help I was able to re-map the hand positions so that the weapons stayed true to the fixed positions.

Also, fixed an ordering error in Jeff's costumes, corrected the quote on Dean's cowboy costume, and added Joseph Gordon Diehard as a costume for the Dean.

Now back to trying to make Sir Riggs Diehard NOT look like Santa or Papa Smurf...
