[PythonCE] Yet one more (minor) change to Python 2.3.4 for Windows/CE

[David L. Kashtan]

This one has been on my list of things to do for a LONG time.
It was really annoying to not be able to interrupt a runaway
Python program.  The current distribution at http://www.validus.com/~kashtan
now has a File Menu item "Interrupt".  It is disabled (gray)
when the Python Shell is waiting for input but is enabled when
the Python Shell is executing commands.  Selecting the "Interrupt"
menu item simulates a keyboard interrupt.
