Mini Shell

"""Define the menu contents, hotkeys, and event bindings.

There is additional configuration information in the EditorWindow class (and
subclasses): the menus are created there based on the menu_specs (class)
variable, and menus not created are silently skipped in the code here.  This
makes it possible, for example, to define a Debug menu which is only present in
the PythonShell window, and a Format menu which is only present in the Editor
windows.
