Code Folding Updates

As you may know the Kate code folding implementation gets some love these days. The last days, several bug fixes dropped in by our GSoC student. And the good news is that if all works well, we’ll be able to backport these fixes so that the code folding is much more robust in our beloved Kate even in KDE 4.7.x. These changes probably fix several crashes that were around since 2005 as well. I believe the word we’re looking for is: owned! :-)
