Escape (annoyingly) exits adolphus-interactive

[ezod]

The Escape key kills adolphus-interactive. Even with self.exit = False in adolphus.interface.Display constructor, the scene window closes. Commit 4422ac8696bcd0e2f517 adds an exit command to the interactive window, so this is no longer necessary, and quite annoying.

A message has been sent to the visualpython-users mailing list asking if this can be disabled from within Python.
