Subject: Allow to cancel while trying to quit and the data was changed.
X-Git-Url: http://git.tdb.fi/?p=ext%2Fsubsurface.git;a=commitdiff_plain;h=1a7695115964887cd19bf1d7e2cef60a2c939482

Allow to cancel while trying to quit and the data was changed.

So far, when trying to quit while the data was changed the offer
was "Save" or "Don't save". Now, you can also "Cancel" which will
bring you back to the main window.

This allows you to re-save the data in another file.
