add missing two-weapon feedback

When dual-wielding and you wield a different weapon, two weapon combat
was silently toggled off even when the new weapon was eligible to be
dual-wielded.  If the verbose flag is On, explicitly tell the player
when wielding something toggles off two-weapon mode.  Wielding '-' is
an exception because you already get told that you're empty handed.
