Add an option to automatically save the list of packages to install/upgrade/uninstall in case there's a guinget upgrade in the list and figure out a way to have the installer restart guinget then open the Apply Changes window again and apply the rest of the changes.

I should probably have guinget do its stuff first then restart and only then do stuff for other apps to make things simpler. This is kinda like what the Windows Store (now called the Microsoft Store, which is confusing because that's also a specific website that Microsoft also offers hardware on) app does where it restarts if it encounters one of its updates.

This option will be on by default to make things easier once it's been thoroughly tested in case someone wants to turn it off. I just don't know how the installer will be handled, but I'll just have to have a way to have it run using the previous user permissions. Not sure how. I do know that on startup it can check to see if there's an in-progress transaction list that's not fully completed, but for safety reasons there needs to be a way to ensure it wasn't tampered by malware or something else. I don't know.
