scrolling windows

1. user interface

Instead of waiting for Icon 9.3.2, I have implemented my own scrolling windows.
When using KE input menu, click on scroll; otherwise use !scroll command.
Arrow keys scroll the window left,right,up,down.
The Home key returns the window to its original position.
The End key terminates the scrolling mode.

2. implementation

Output is written to a hidden 81 row by 800 column console window.
A 24 row by 80 column subwindow is copied to the scroll window.

The 81 row limit is due to a bug in Windows Icon 9.3.1. When Icon 9.3.2
becomes available, I will increase the limit to 240 rows.
