Small patch for kdf to improve the usability

[Wearenotalone]

Hi there,
at the moment kdf remembers only the hidden columns. The sortorder of
the rows and the columns is lost after each close. The following small
patch saves this information of the QTreeView header:

Unfortunately, I do not know where to send this patch, except to this
mailing list. Therefore, it would be nice if someone could review and
possibly commit this patch.

Sincerely,
