Address bug #126768

Bug report: https://bz.apache.org/ooo/show_bug.cgi?id=126768

Applying values of the <svg:title> and <svg:desc> elements was failing due to the type of the SwXFrame's SwModify::pRegisteredIn attribute.
A ``winner'' image is set its name successfully. Setting the above values to the same winner image also succeeds.

This PR must be checked against document with images, and hyperlinks as well.

Looks great!
Maybe we can get it into 4.1.16-RC1?

The document attached to bug 126768 was crashing on Windows. The reason was an out-of-bound access in the vcl library, that was only detectable after merging the commit in pr #450

This PR is IMHO ready to be merged.

FYI the document also failed to open on Linux. Should I Merge it now? Or is it up to you to do that?

I will try a new build now!

Builds fine and I could open the files without problem now!

LGTM!

Funny fact: After saving the files with this version, I can also open them with AOO 4.1.16.
Re-saving them with LO 2.8 makes them unreadable again with AOO 4.1.16.
