Gamgi->Exit asks confirmation to close GAMGI.

Because this is a very sensitive operation, users are not allowed to perform any other task until answering the question (not even consulting the Help).

Pressing Ok, GAMGI closes all windows and exits, without further notice and without saving any data.

Pressing Ctrl C over any GAMGI window or over the launching xterm window works exactly as selecting Gamgi->Exit. Pressing the End key over any GAMGI window has the same effect.

When only one top window is open, selecting Window->Close has exactly the same effect as selecting Gamgi->Exit.
