WIP: Better Handling of Read-Only Files
Based on the suggestions posted in #126 (closed), these commits handle read-only files in a user-readable manner. When a read-only file is open, using the Ctrl-S shortcut opens the "Save As" dialog instead of simply being ignored. And, when closing the application with an unsaved read-only file open, the user is also informed as to why the file must be saved as another.
I do want to note that handling of Ctrl-S also now means that files without changes will also open the "Save As" dialog. That might not be a desirable outcome, so I'll mark this as WIP for now.
