#2 losed-unsaved-info-message when closing a saved project

When I close Debreate it always inform me that unsaved informations will get lost.
This happens also when the project is still saved and unchanged.

This shouldn't. Debreate should know if the project is in an unsaved state or not.

This is something I have thought about doing for a while but haven't put in the effort to implement yet. It will be added in the future, hopefully.
