quest artifact handling (trunk only)

     When the hero receives the quest artifact "got it" message, set the
artifact's dknown bit in case the hero is blinded.  That message describes
the object by name, effectively the same as seeing it up close.  (This
would have prevented the "now wearing an Eyes of the Overworld" grammar bug
for monks but not for non-monks, so the previous fix is still necessary.)
