[gimp/metadata-browser: 26/45] New test case to test import/edit/export/import.

[Roman Joost <romanofski src gnome org>]

commit 9195f5c7241b86b4a82fbd1a56bb8473908a78ea
Author: Roman Joost <roman bromeco de>
Date:   Tue Sep 27 21:09:19 2011 +1000

    New test case to test import/edit/export/import.
    
    This test should assure that imported data is not touched until edited.
    If it is edited it should be only merged on export.
