item actions for '* ) [ = " (' commands

Make the various item-in-use commands put up a menu--which allows
choosing an item for context-sensitive item action--if/when preceded
by the 'm' prefix.  Some of them do that even without the prefix ('*',
'[', or '=' when more than one ring is worn).  By default '(' shows
primary weapon, then secondary one if dual-wielding.  'm (' shows a
menu of primary, alternate whether dual-wielding it or not, and quiver.
