Version 0.2.13 Released

Updates:

• The drag chute has finally received the attention to detail that pretty much everything else has.  This isn't final polish yet, but at least it is more than the quick test feature that it used to be.  There is new art and the chute inflates with motion.  The collider on the chute has finally been enabled after resolving most scenarios where the chute might get stuck on the wrong side of the track barriers.  This can still happen through no direct fault of the driver, but the precise scenario is extremely rare and, thus, dubbed part of the chaos of the game (don't get rear-ended while diagonally backed into a wall).  Anyhow, the chute can now get tangled on some objects such as other cars -- but this feature has been made to also be fairly forgiving and should untangle fairly easily.
