Overview
Comment:Enable switching between windows with left/right keys

- Oh my, I've ended up using pointers to pointers already! Use this so
can switch the menu/win "pointing" at with left and right keys and
then scroll up down the active one.
- Also means need to just use plain getch and not wgetch as don't want
to limit input to one window.

I still don't get what determines an active window. Is it just cursor
position?

First attempt at getting two menus side by side

Tricky bit was that have to re-create my_items. I thought I'd be able to
re-use that for the sake of this test. But without recreating it the
second menu is blank. check-in: 8fab8d5ebf user: atomicules@lavabit.com tags: origin/master, trunk
