Changelog / testing notes pop-up
- Help menu item for showing a window with:
- Scrollable view of a text file holding full bottom-to-top sorted changelog and current testing notes (ie a section of "it would be helpful to have testing efforts focus on these areas:").
- "Show this on new version launch" checkbox.
- Also save hash of the changelog-and-testing-notes file to user settings.
- On launch, if setting for "Show this on new version launch" checkbox is set and the changelog-and-testing-notes hash differ from the one in settings, show the window.
