ppokorny 5d6406feb1 When changing from a widget-based storage (that was, in retrospect a
horrible hack) to a screen data item, I neglected to fix the code that
doles out key events to screens and clients.  This meant screens didn't
get keys.  It's now fixed.

input.c
Handles keypad (and other?) input from the user.
Currently, the keys are as follows:
Context Key Function
------- --- --------
Normal "normal" context is handled in this source file.
A Pause/Continue
B Back(Go to previous screen)
C Forward(Go to next screen)
D Open main menu
E-Z Sent to client, if any; ignored otherwise
(menu keys are not handled here, but in the menu code)
Menu
A Enter/select
B Up/Left
C Down/Right
D Exit/Cancel
E-Z Ignored
