[request] IDE: ask whether to save unsaved changes before showing file dialog

[Edu]

version: X-1.0rc3
OS: Ubuntu 10.04

1. Type something in the editor pane.
2. Without saving, exit Sikuli

Result: The file dialog is shown. If you click Cancel, another dialog is shown, asking you whether you want to save the changes. If you click Yes, the file dialog is shown again. If you click Cancel in the file dialog again, Sikuli exits without saving.

Expected result: User is first asked whether she wants to save the changes. If Yes, the file dialog is shown. If no, Sikuli exits without saving. If the file dialog is cancelled, Sikuli exits without saving. (This is how most other programs work.)
