[Reportbug-maint] Bug#565140: reportbug: GTK UI should have 'Back' button as well as 'Forward'

[Matijs van Zuijlen]

Package: reportbug
Version: 4.10
Severity: normal

The reportbug GTK front end vaguely imitates a Druid/Wizard-style interface
by showing a 'Forward' button. Unfortunately, there is no 'Back' button.
Pressing the Cancel button instead completely ends the session without any
warning.

Also, some subtasks in reportbug (such as adding tags) would usually be
handled by modal dialogs. This makes it even more tempting to press the
Cancel button: The expected behavior is that the task is canceled, not the
entire session.

Suggested changes:
- Add a Back button to go to the previous screen.
- Add a confirmation dialog to the Cancel action.
- Use modal dialogs where appropriate.
