unsaved changes lost when cancelling save

[rew]

When you hit "quit" when there are unsaved changes, you get a warning popup.

So you hit "save".

When it asks for the filename, you think: Wait, let's try XYZ. so instead of saving you want to go back. So you hit "cancel".

Hugin now exists without saving. Ooops.

The warning popup also has a cancel. That will cancel the quit and not lose your data. That the "cancel" in the "enter filename" would cancel the save and quit instantly surprised me.

I agree, that in a sense this makes sense, but I can easily imagine that others would be surprised by this too.

I have solved the problem by adding a new bool variable in the MainFrame
class. This variable is required to determine whether the confirmation
dialog was closed with the Cancel button. The patch is attached.

No nagging please. We as developer are automatic notifitied when there are changes to the bug tracker.
Your patch does not work if the saving was not sucessful.
Therefore pushed a simplier solution which should also consider the case that the file could not saved.
