Option to remove old app on macOS

[Han Sooloo]

On macOS, I typically start the app by searching for app name in Spotlight, i.e., Cmd-Space, type "Tun", and usually within 3 letters, Tunnelblick is found.

However, after an app update, there is a `Tunnelblick-old.app` left in the `/Applications` folder, and Spotlight now finds 2 Tunnelblick apps.  And, sometimes, the first selection returned is the old app.

Wonder if there is an option for the updater to NOT leave the old app in the `/Applications` folder, and simply put it in the trash.

I don't understand why the old app is left there, since every other app I know of will update itself cleanly.

I agree. The next version of Tunnelblick will remove all old copies.
