another Kirigami patch

[Dirk Hohndel]

This one is not directly related to the feedback that I had already
collected, so instead of constantly replying to myself, I'll start a new
email.

If a page in a PageRow updates it title but the page object in the page
stack doesn't change, Kirigami doesn't notice and happily shows the now
outdated bread crumbs in the title. I couldn't figure out a way for
the ApplicationHeader to notice that one of the titles has changed, so I
turned this around and offered the app a way to tell Kirigami that a title
had changed.

/D

Subject: [PATCH 4/4] Allow the application to notify Kirigami about changed
 title

Simply calling header.updateBreadCrumbs() makes sure that the bread crumbs
in the title are correct.
