guess: Much more efficient keyboard interface

Browse Source 
Now rather than mucking around with the cursor keys, you can just type a
four-digit number and press Enter.  Of course, if you still want to muck
around with the cursor keys they work the same as before.

Since Backspace was already assigned to clear the peg under the cursor,
I haven't co-opted it for the obvious action of clearing the peg to the
left of the cursor and moving the cursor left.  The left arrow key is a
reasonable alternative anyway.

For consistency, 'L' now labels the pegs with numbers rather than
letters, and is documented.
