Disable quit in tray during snapshot process

[rak-phillip]

This adds an id for the "quit" context menu item in the tray menu and filtering by using array methods.

That's fine, but do note that people can still quit via the dock icon, IIRC. And there's also the main menu.

The scope of the issue covers the tray menu, but I can investigate and expand this PR to the dock icon.. I don't think we need to concern ourselves with the main menu, as interactions with it should be disabled altogether during snapshot operations.

Nah, it's fine to do things in a follow-up PR; I just wanted to note that so you're aware (since you're in a better position to know what other things need to be done in the area).

This does not appear to be the case, at least on macOS. The application menu remains fully functional during the operation. I'm also not sure how the menu should be disabled; it would be done by disabling individual menu items. I'm not sure if you should ever disable the "File | Quit" menu entry, or if this should just cancel the snapshot operation and then exit the app? (I realize that "Cancel" is not yet implemented, but let's assume it is).

But this should be a separate issue. Keep this one to the tray functionality!

Of course, the global menu on macOS wouldn't be blocked by any dialogs.. I created two issues so that we can follow-up and address these changes
