new featurette: '-' in inventory menu

Requested during beta testing last year, include a menu entry of
"- - your bare hands" (or "your gloved hands") for wielding,
"- - empty quiver" for readying quiver,
"- - your fingertip" for engraving, or
"- - your fingers" for applying grease
if the user responds with '?' or '*' at the
"What do you want to {wield|ready|write with|grease}? [- abc or ?*]"
getobj prompt.  (First dash is inventory selector 'letter', second
dash is menu separator between the letter and its choice description.)
