[Idle-dev] Deprecate running IDLE without a subprocess

[Roger Serwy]

The auto-saving feature only saves the one editor window, not all of 
them. It is possible to lose unsaved work in yet-to-be executed code in 
other editor windows.

Presently, PyShell.py and a few other extensions have code paths to 
handle running with and without the subprocess. Requiring a subprocess  
would be simplify the code.
