SettingsWindow now notices if the window is marked as modified, and shows a confirmation pop-up to check if the user wants to apply or discard their changes. It automatically marks the window as unmodified after restoring defaults or applying the changes, but each Tab subclass needs to call `set_modified(true)` when the user modifies things. The "Apply" button is automatically disabled when there are no unsaved changes to be applied.
