Summary: IDLE Shell window RunScript warning 

Initial Comment:
Alter IDLE's ScriptBinding.py to provide a warning if 
called from the shell window instead of a program 
window.

Also, consider providing a warning for File Save or 
SaveAs from the shell window.

The purpose of the warnings is handle a newbie problem 
of typing a program in the interpreter, trying to save 
it from there with File SaveAs mymprog.py, and trying 
to run it with F5 from the shell window.

Here is an except of a dialogue on help@python.org:

[beginner]
'''I have several programs I've written and saved.  I 
have saved them as ' save ' , ' save as ' , ' save 
copy ';  but when I try to run the program I get the 
same response from the GUI, name error: name ' ' not 
defined.  The exact procedure I use is: I bring up the 
GUI; click on file; click open; click the program I 
want to run.  Then when that window opens I click 
Edit; then Run Script. When that opens I type ; 
filename ( )  to run the program and all I get is " 
filename not defined" which I'm assuming means I have 
to rewrite the entire program each time I want to use 
it.'''

[helper]
'''IDLE has an interpreted mode (indicated by the >>> 
prompt) -- that is not the place to write and save 
your program.  Select File New to create a new blank 
page for your program. Type in the program (only 
once!) and select File SaveAs myprog.py.  Next, press 
F5 which will run your program. '''

[beginner]
''' So, your saying WRITE the program on the blank 
screen , the one without the prompts, etc ? Then save 
it to file "save as" ?  I never knew that was the way 
it's to be done. I've written every program I've done 
on the idle screen.  I really appreciate your help '''

Yes, I follow the Idle-dev maillist but prefer to work on 
other Python projects for now (focusing on the Docs, 
clearing bugs, feeding slices to getitem, itertools, an 
observer pattern prototype, and generator attributes).

Wanted this patch as a minimally invasive usabilty fix 
until the IDLEFORK guys have done the deeper magic.

Raymond, are you aware of the IDLEFORK project?
http://idlefork.sourceforge.net/
It desperately needs developers.
Maybe you can help out there?
We will gladly add you as a developer.

(I say this because the issue here is already addressed
there, in a much different way, but that won't help us until
the idle fork has been ported back...)

The attached 5 line patch disables the shell window's menu 
and key bindings for script actions.  It leaves them intact 
for other windows.

This addresses a common beginner problem (there have been 
multiple requests on the python-help maillist) without 
otherwise impacting functionality.
