Add Makefile and config.mk

Probably overkill for such a tiny file, but good practice for me. check-in: fc1d33f903 user: atomicules@lavabit.com tags: origin/master, trunk

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? check-in: db667542ca user: atomicules@lavabit.com tags: origin/master, trunk
