[issue24799] IDLE should detect changes to open files by other processes

[Al Sweigart]

New submission from Al Sweigart:

Many IDEs will check for changes to their opened files made by other programs. This is usually done with a quick check when the IDE's window gets focus.

A dialog will tell the user the file has changed on disk and ask if they want to reload it. This dialog is only shown when the file has changed AND there are unsaved changes made in the editor. Otherwise, the file changes are just silently reloaded. (This is the behavior of Sublime Text.)
