blindfolds and more (trunk only)

blindfolds and more (trunk only)

1) the change yesterday to mark inventory as seen when recovering from
   blindness neglected to handle blindfold removal;
2) fix grammar when using 'R' or 'a' to try to remove cursed lenses
   (now "they are cursed" instead of "it is cursed");
3) attempting to put on a wielded or quivered blindfold, amulet, or ring
   and failing because of already wearing one (or two in the case of
   rings, where cursed gloves and ESC at "which ring-finger?" prompt got
   similar result) unwielded/unquivered item rather than leave it as is.
