option to prevent unintended close

[smolin]

kitty is wonderful, thank you very much!

Is your feature request related to a problem? Please describe.
I'm always frustrated when I hit command-q or command-w and the window closes, losing my shell state.

Describe the solution you'd like
I would like a dialog open asking "do you really want to close this window? yes/no"

Describe alternatives you've considered
Um ... I've looked through the docs and issues and didn't see this as an option?

Additional context
Add any other context or screenshots about the feature request here.
MacOS 10.14.6, kitty 0.17.4

Thanks Luflosi! I shoulda updated first of course.

This is almost but not quite perfect - set to "1" it:

- confirms closing the application with command-q
- confirms closing windows when clicking on the red X circle button
- confirms closing windows with command-w when there are more than one shell

but it does not confirm closing a window with command-w when there is only one shell. The description says "at least this number of kitty windows" so I think it's not counting correctly....

As I recall cmd+w is close_tab, correct? The option is for closing OS windows, not tabs. It might make sense to either extend it to also apply to tabs or to have a new option for tabs.
