Allow disabling the Exit dialog

[alayham]

• A clear and concise description of what the bug is.
  I use version 2.5.3 on Debian with the KDE desktop. I want my computer to shut down when I am not using it. When novelWriter is open, the shutdown is held indefinitely by the close dialog.

I understand the need to warn users when data can be lost, but in this case all data is saved automatically. Therefore, this dialog is not as useful as in normal word processing apps, and it causes problems.

• Steps to reproduce the behavior
  Open a novel on KDE Plasma (not tested on other systems)
  configure your computer to shut down automatically after a few minutes of inactivity.
  Wait for the shutdown. It will be stopped by the exit dialog. The dialog will remain open and prevent shutdown.
• A clear and concise description of what you expected to happen.
  Either a configurable countdown for shutdown, or an option to disable this dialog.
• If applicable, add screenshots to help explain your problem.
  See above
• If the error dialog popped up, copy/paste the content here.

This is not a bug. The dialog is there to prevent accidentally closing the app, a very annoying thing that too many applications allow.

I could potentially add a way to disable the dialog as an option in Preferences.

That is very much appreciated.
Thank you very much for the amazing app.
