enlightenment about bones

"You have disabled loading of bones levels" (during play) and
"You disabled loading of bones levels" (end of game disclosure)
both clearly refer to the player rather than the hero.
"You have never encountered a bones level" is accurate for current
hero but not necessarily accurate for the player.  Rephrase it.

Also, if OPTIONS=!bones is set and the hero just died, extend
"You disabled loading of bones levels" during disclosure to
"You disabled loading and storing of bones levels" (even in the
case where bones wouldn't be saved anyway).
