Ask to Save Upon Exit

[cs50ad]

Upon exiting or creating a new scene, there should be a warning if we haven't saved the scene.

This is useful because it prevents us from losing a large scene with many references if we forgot to save it.

Thank you for this incredible software!

Is there a reason it can't just save constantly so I don't need to manually save? I assumed it was already saving work and lost everything (my first attempt at using it to try it out).
