[Tutor] remap tab key to 4 spaces in a Tkinter text box

The tab option in a text widget lets you enter the number of centimeters to space over, but this option is truly useless when you want real live spaces instead.

My Tkinter is a bit rusty, but the latter approach might be the one to
take.  Just remember to return 'break' at the end of your callback.
This prevents the event from being passed on to the text widget.
