Exiting Tkinter when using IDLE

[Jason Harper]

Ok, this hasn't been tested very well, but it seems to make
IDLE+subprocess work as I'd want it to with Tkinter applications.  Just
replace Lib/idlelib/run.py with this file:

You can even do interactive experimentation with Tkinter now.  Try this:

>>> from Tkinter import *
>>> root = Tk()
>>> mainloop()

At this point, IDLE's shell window would normally cease to accept input.
 Now, you immediately get a prompt back, although internally it's
working rather differently than a normal prompt.  Meanwhile, the Tk
window is fully movable, resizable, and closable.

>>> Button(root, text="spam!").pack()

The button immediately appears and is clickable (of course, it doesn't
do much).

>>> Button(root, text="die!", command=root.destroy).pack()

If you use this button, or close the window, the mainloop will exit. 
You'll need to create a new root window, and start a new mainloop() if
you want to do anything further with Tk.
