commit 5dc78980f4c1061ca58eab85ec5df47e55a3fff7
Author: Michael Natterer <mitch gimp org>

app: implement pattern saving in the core
Add GimpData::save() implementation to GimpPattern, and change some
glue code to make patterns editable.
Also implement GimpData::duplicate() in GimpPatternClipboard, which
makes it possible to simply copy an area and duplicate the clipboard
pattern to create a new persistent pattern.
(cherry picked from commit e93fd73face1e0e26484c9f5f9a938479ac61a9d)
