Alias /quit and /q to /exit

[harleypig]

When asking questions or reporting issues, it is very helpful if you can include:

• Aider version 0.21.1

Just a minor request. I use cli db apps, all of which have an exit command of the form /q, /quit or .quit. Also, python's repl is quit().

Not a biggie, just when you have some extra tuits.
