breaking polyselfless conduct

Because the description seen by the player is "you have never changed
form" rather than "you have never polymorphed yourself", make death by fully
turning into green slime (even if that death is avoided via lifesaving)
violate the conduct.  Suggested by <Someone> 9-Dec-2004.  Likewise, eating
a mimic corpse and temporarily turning yourself into a pile of gold also
violates that conduct.  Mentioned by someone--probably <Someone>, or possibly in
the newsgroup--a long time ago.
