Bug: Pinstick no longer prompts the user to close when saved data is entered. #13

While possibly no longer required, The app, which claims to security process data in a privacy focused manner, should disclose of all features.
Previously Jot would disclose to the user whenever the app was being closed with data, now that PinStick saves the user's last written data, it is not strictly functional.

However, for the sake of user's privacy, I believe when data is entered, the user should still be prompted when they close the PinStick Window.
When they do so, we should ask the user what they want done with their data, it shredded and deleted, or if they want to retain the data saved to memory. We should respect their decision.

We will need to respect the protocols of all versions of the app for doing this, in macOS this presents as a visible "dot" in the close button, in windows and linux this is the standard popup before initiating the close action.
