Options to create the character blind or nudist

For those pro players who really want to try their hand
at that zen samurai, without needing to reroll thousands
of times to start with blindfold.  Nudist starts without
any armor, and keeps tabs whether you wore any during
the game, for even more bragging rights.

Also makes the Book of the Dead readable even while
blind, for obvious reasons.
